Trendy Character Poster Design

Title: Transform uploaded portraits into a complete trendy character poster.

Prompt: Convert uploaded portraits into a complete trendy character poster.

The focus is not on realistic reproduction, but on extracting character recognition features and reconstructing them into roles. Retain the original character's hairstyle, face shape, temperament, expressions, outfit colors, posture, shoes, and important accessories, allowing people to see the original character's features, but the character cannot be realistic.

Character style requirements:
Exaggerated trendy characters, street youthful vibes, relaxed, confident, and flamboyant, with a digital thick-smudged poster style.

Character proportions requirements:
The head is slightly large, but don't use a chibi style;
The neck is slightly longer;
The torso is relatively small;
The body is thin and long;
The limbs are noticeably elongated;
The arms are slender and long, with distinct bends on the elbows;
Wrists are slender;
The palm is slightly larger;
Fingers are slender and long, with clearly defined joints and posture;
Legs are slender and long, with clear knee flexes;
slender ankles;
Shoes must be noticeably enlarged, with thick soles and a trendy toy feel.
If the character is not wearing shoes, or wearing slippers, sandals, or barefoot:
The feet should also be graphically and exaggerated.
The number of toes is correct, the structure of the foot is clear, the ankle is slender, and the foot contour has geometric and design flair.
The soles can be slightly enlarged, the toe structure is clear, and the proportions of the instep, ankle, and sole are well designed.
The feet should be designed as graphic characters, avoiding realistic foot shapes and drawing them as blurry, deformed, multitoe, or attached toes.

Character Form Requirements:
The body should not approach the true human proportions.
The limbs should have a sense of geometry, folded lines, and elongated color blocks.
The elbows, knees, wrists, and ankles should have clear structures.
Joints can be exaggerated, but the structure must be believable.
The character's posture should be relaxed and natural, including squatting, half-squatting, sitting on the ground, making hand gestures, spreading arms, or looking sideways at the camera.
Don't stand stiffly.

Hand requirements:
The hand is one of the key points in the composition.
Fingers should be slender, flexible, and have clear joints.
Gestures should be natural, designed, and street-oriented.
If it's the Bié gesture, the index and middle fingers should be clearly separated, and the other fingers should naturally bend.
Do not overdo or underply, do not stick fingers together, do not blur the hand, do not deform the hand.

Facial features treatment:
The facial features must be graphic, simplified, and exaggerated.
Don't want realistic skin texture, don't want real eye highlights, don't want realistic portrait impressions.
Eyebrows, eyes, nose, and mouth are outlined with design lines and large color blocks.
Expressions can be more exaggerated, more confident, and more distinctive than in the original photos.

Background treatment:
The background must also match the character's style and cannot be realistic.
Reconstruct all the original photos—mountains, water, tents, stones, street scenes, rooms, furniture, and objects—into graphic color blocks, impasto brushstrokes, collage fragments, doodle lines, semi-transparent geometric shapes, and abstract poster elements.
The background can refer to the scene structure of the original photo, but it must be flattened, simplified, symbolized, and posterized.
Avoid stylized characters with realistic backgrounds that feel disjointed.

Poster Visuals:
The image should not be just a person with a white background.
Add scene-appropriate doodles, handwritten marks, arrows, stickers, tape, rough brushes, abstract symbols, and collage blocks.
Doodle text should be lightly embellished, using FREE, VIBE, DAILY, CHILL, PLAY, SUMMER, WILD, GOOD VIBE, or Chinese phrases like outing, relaxed feeling, current state, and a bit freer.
Do not cover faces or gestures in text, do not turn it into a formal title, and do not garbled text.

Overall style:
modern urban character poster,
stylized streetwear character design,
exaggerated proportions,
long thin limbs,
angular joints,
oversized shoes,
graphic facial features,
expressive hands,
long fingers,
digital gouache painting,
rough brush strokes,
blocky color shapes,
loose painterly edges,
abstract poster background,
collage elements,
graffiti lines,
handwritten notes,
urban art zine style,
fashion editorial poster,
low saturation color palette,
off-white background,
strong poster composition.

Final Result:
A high-end trendy character poster.
The characters have clear joints, long limbs, detailed fingers, exaggerated shoes, relaxed postures, and distinctive expressions.
The background should also be unified into impasto, collage, graffiti, and graphic language for posters.
Negative prompts:
Don't want realistic characters, don't use realistic portraits, don't use normal real proportions, don't want rounded chibi versions, don't want children's cartoons, don't want anime, don't use 3D rendering, don't feel plastic, don't want real skin textures, don't use real eye highlights.

Do not have short or thick limbs, do not wear normal shoe sizes, do not stand stiffly, do not have no joints, do not have blurred joints, do not smudge fingers, do not have too many fingers, do not under-to-to-speak, do not stick fingers, do not have deformed hands.

Don't use realistic backgrounds, don't use real photo backgrounds, don't want character illustrations but feel disconnected from realistic backgrounds, don't use complex realistic landscapes, don't use real photographic light and shadow, don't use formal ad headlines, don't use garbled text, don't use watermarks, don't use logos.
