Reference Images & Generation Testing
DRAFT 3 · CHARACTER TESTING · MAY 2026
Character reference sheet on a clean white background. A cartoon baby octopus (Ollie) displayed flat in a character sheet pose, full body visible with all eight flowing soft-curved arms spread outward. FACE: Big round dark pill-shaped pupils with warm golden star catchlights. Small gentle curved mouth. Smooth perfectly rounded plump head with NO ears, NO bumps. BODY: Fine SMALL stipple brush dots (gold, orange, yellow, white) in delicate stipple pattern across entire body. Eight flowing soft-curved arms. COLOR: Warm Golden-Amber (#E8A735) as primary skin tone. Light orange highlights on the top of the head. Yellow-gold mid-tones across the body. Cream white on the underside. Gold foil metallic stipple dots throughout. RENDERING: Painted gouache and watercolor character on a flat white background. Clean character reference format. The octopus looks like a handcrafted illustration with gold foil embossing detail. Warm, inviting, luxurious picture book quality. The masterpiece-level gold foil stipple is the signature visual -- thousands of fine gold dots catching light across every surface of the body. Clean white background. No environment. No underwater elements. Character only. No text.
A single solid natural Tahitian pearl on a clean white background. Perfectly round, smooth, polished nacre surface with beautiful pearlescent iridescent quality -- mother-of-pearl sheen with soft pink, green, gold, and cream tones shifting across the surface like a real pearl. The surface has intricate gold foil stipple detail -- fine, delicate gold flecks catching light across the nacre. Eyes are warm yellow upside-down half U-shapes with rounded end lines, glowing softly from INSIDE the pearl, projected through the nacre surface as pure warm yellow light -- like light passing through mother-of-pearl. The eyes convey a gentle, content, neutral expression. The pearl looks undeniably real and authentic -- luxurious, tactile, you can almost feel the smooth cool nacre surface. Light catches the pearlescent surface creating soft rainbow iridescence. The pearl sits naturally on the white background with a subtle shadow grounding it. Golf-ball sized pearl. Photorealistic pearl material with the eyes as the only stylized element. 1:1 aspect ratio. Character study on white background.
Create NEW dynamic character references that address the founder's feedback. Current refs are too static and rigid. Need dynamism, flow, correct detail rendering, and proper eye illumination for Dot.
Gentle 20-degree tilt from horizontal. Eyes glowing from inside. Floating in clear water.
35-degree angle, looking upward. Stronger internal glow. Dynamic orientation.
Drifting through coral. Nacre catching warm reef light. Environmental interaction.
Tight crop on nacre surface and glowing eyes. Emphasis on "light from within" quality.
Deeper blue-teal environment. Eyes warm yellow contrasting cool surroundings.
Both characters in frame. Establishing relative scale and dynamic interaction.
Dynamic swimming pose. Arms trailing and curling with water current. Immersed in environment.
Arms extended in multiple directions. Engaged with environment. Curiosity pose.
Gold stipple on head/arms, gold dots between eyes, gold foil iris, pink cheek blush.
Mid-turn body twist. Arms flowing in different directions. 3D volume and movement.
Happy expression. Expressive playful arm positions. Bubbles and particles.
Partially hidden among warm coral. Arms wrapped around branches. Environmental integration.

Turnaround sheets NOT recommended (Ollie is radially symmetrical, Dot is a sphere). Single canonical references work better for these character types. Remove "cartoon/illustrated" language from prompts. Add physicality anchors: "gold foil", "nacre surface", "iridescent". GPT-Image-2 supports up to 16 reference images with strong native consistency. Recommended set: Ollie 3 refs (neutral, swimming, close-up), Dot 2 refs (standard, in-context).
"The problem that we have most often with DOT is that the eyes aren't the right shape and don't appear like real lights shining through. That's the quality that we need to get."
"It's like it's a real illuminated light shining through the surface that's like this pearlescent nacre surface"
"Also some sense that she's like floating in water in the scenes"
"DOT's face should never be straight on, in perfect alignment with the horizon. She should be kind of floating round and tilted"
"She's a three-dimensional sphere, so we need to bring that into her character reference and build up the right prompts and reference images"
"Same with OLLI: he needs to look really immersed and like he is in flow with the water around him"
"The current character references are kind of more static and rigid, but we need more dynamism in both of the characters"
"He has this really intentional hand-detailed gold stipple-dot style around his head and on his arms"
"He has just a few little gold dots in between his eyes"
"His irises should have this gold foil effect"
"His pupils and his eyes have this clear kind of sheen, and his pupils have this natural light glimmer"
"He has just a subtle pink kind of blush on his cheeks"
D1: "The lights kind of look like they're reflecting on the surface of her shell, her outer casing. They should be like shining through it. On the tilted Dot version she looks like she's got like a texture effect on some kind of texture effect on her surface. She should be a smooth pearlescent."
D2: "On the deep tilts concept there's like a bright light shining through her body in the middle, we need to remove that."
D3 (BEST): "D3 In Motion, that one is the best. She's got the reflective surface, that looks cool. Maybe we can make it a little less reflective, like almost like a real pearl, so like not as shiny."
D4: "D4 close up, the Pearl Dot surface is black in this. We need it to be pearlescent like a real pearl and the light again is like reflecting on the surface, it's not shining through. We need to shine through."
D5: "The deep water, it looks close. I think the surface is a little too dark basically based off the lighting of the scene."
D6: "The with Ollie scene, the Ollie character should be our actual Ollie character. We need to do an illustrated Ollie and a 3D Ollie. None of the Ollies are quite what we're looking for."
"They don't look like they're different concepts from the 3D ones, they look pretty much the same and they're having some artifacts like textures on the surface of Dot and Dot being the wrong color."
"Dot's eyes being wrong in the D4 close-up for the illustrated one, and the size proportion with Ollie in both of the dot concepts is wrong. Dot is too big."
"I don't know why we have like 3D plus illustrated. We have an illustrated concept that should be used for the illustrated version. We shouldn't be doing like 3D plus illustrated."
"For the 3D version of Ollie he shouldn't have ears. We don't want him to have ears. He always needs a mouth. O3 is missing a mouth."
"His arms are too long."
"I think he should be in water like blue water in all of these, like the O1."
"They're all looking like a little bit almost like cartoony and like computer generated and not like hand created artwork in like a 3D like realistic photograph scene."
"O1 is close but it still has like a computer generated effect and the arms are too long."
"I think maybe like his mouth needs to be like a little bit lower from his eyes."
"The O4, O5, O6, O2, O3 these concepts don't really work."
"None of these concepts look right. They should be using that illustrated concept. It's called Ollie Illustrated, it's on the character reference page."
"Those all need to be redone as well and that too needs to look like realistic illustration. Not like computer generated."
"We need to remove any prompting about like cartoon or children's book or children's illustration. We just need it to be like hand painted artwork."
The 1-reference images above used only the 3D reference. The 2-reference images below used both the 3D and illustrated references. Compare each variant across both sets to evaluate whether the additional illustrated reference improves consistency, detail rendering, and character fidelity.
