프롬프트 1 — 정석 캐릭터 시트 스타일 (Exact Character Sheet Style)

기본적인 캐릭터 디자인 보드 레이아웃으로, 7개 핵심 섹션과 깔끔한 스튜디오 백드롭을 기반으로 제작됩니다.

Use the uploaded male reference image as the primary identity and appearance reference. Create a professional, high-resolution character reference sheet of the SAME male person, arranged exactly like a premium character/model design board. Do not change his facial identity, facial proportions, hairstyle, skin tone, athletic body structure, or overall appearance. The character should remain recognizable throughout every panel.

Create a clean white studio background with thin light-gray dividing lines and a professional editorial layout containing seven clearly separated sections.

1. CHARACTER PROFILE: Include a large realistic close-up portrait of the same male character along with general character information such as role, approximate age, height, athletic body type, confident personality, distinctive facial features, hairstyle, eyebrows, eyes, jawline, nose, lips, skin tone and overall fashion style. Add coordinated color swatches based on the red tracksuit, white shirt, green accent, black/dark details and neutral tones.

2. FULL-BODY TURNAROUND: Show the exact same male character in full body from FRONT, 3/4 VIEW, SIDE VIEW and BACK VIEW. Keep his red tracksuit jacket, red track pants, white T-shirt, white sneakers, hairstyle and body proportions consistent in every view. Neutral standing posture, professional studio lighting, full body visible from head to shoes.

3. FACE AND IDENTITY DETAILS: Show three large realistic facial studies of the same man: FRONT, PROFILE and 3/4 VIEW. Keep his exact recognizable facial structure, strong jawline, defined cheekbones, dark eyebrows, short styled black hair, straight nose and natural masculine appearance. Add small descriptive notes underneath.

4. EXPRESSION SHEET: Create ten separate head-and-shoulder portraits of the same man with different expressions: NEUTRAL, HAPPY, SMILING, PLAYFUL, SAD, SURPRISED, THINKING, CONFIDENT, WORRIED and CALM. The identity must remain exactly consistent.

5. POSE AND BODY LANGUAGE: Show six full-body poses of the same man: STANDING, WALKING, SITTING, RELAXED, ARMS CROSSED and LOOKING BACK. Keep the same red tracksuit outfit and white sneakers in every pose.

6. COSTUME DETAILS: Add close-up panels showing the neckline and white T-shirt, red jacket zipper, sleeve detail, waistband/drawstring, back of jacket, red tracksuit fabric, zipper hardware, T-shirt graphic detail and white sneakers. Make every detail realistic and consistent with the reference outfit.

7. COLOR AND MATERIAL PALETTE: Add clean color swatches with HEX codes for the main red, white, green, black and neutral colors. Beside them show realistic material references for tracksuit fabric, cotton T-shirt, zipper metal, ribbed cuffs, sneaker leather and drawstring material.

Use photorealistic photography, sharp facial details, realistic skin texture, accurate anatomy, professional fashion-catalog lighting, consistent proportions, clean white background, high resolution and extremely consistent character identity. Do not introduce another person. No female character. No unnecessary text or decorative elements. Keep the entire sheet visually similar to a professional character-development/model reference board.

프롬프트 2 — 시네마틱 디테일 버전 (More Detailed / Cinematic Version)

인물의 피부 질감, 원단 질감, 자연스러운 그림자와 조명 디테일을 강화한 고품질 버전입니다.

Create a premium photorealistic male character turnaround and identity sheet using the uploaded reference photo as the strict visual reference. The generated character must be the SAME male person shown in the reference, with the same recognizable face, short black hairstyle, facial proportions, skin tone, athletic muscular physique and confident masculine appearance. Preserve his identity consistently across every single image panel.

Design the entire image as a professional character-design presentation board on a clean white and very light-gray studio background. Use a structured 7-section grid with thin borders, small professional labels, balanced spacing and high-end fashion/model portfolio aesthetics.

SECTION 1 — CHARACTER PROFILE:
Place a large close-up portrait of the male character. Beside it include a concise profile describing him as an athletic, fit, confident and stylish male model. Include approximate age range, height, body type, personality, distinctive features, hairstyle, eyebrows, eyes, jawline, nose, lips, skin tone and overall fashion personality. Add six coordinated color swatches taken from his outfit.

SECTION 2 — FULL-BODY TURNAROUND:
Generate four full-body studio views of exactly the same character: front, three-quarter, side and back. The outfit must remain identical: bright red zip-up tracksuit jacket, matching red track pants, white T-shirt underneath with the same green/red accent treatment, and clean white sneakers. Maintain identical body proportions, hairstyle and facial identity in every view. Use neutral professional poses and soft studio lighting.

SECTION 3 — FACE AND IDENTITY:
Create detailed close-up portraits from front, side profile and three-quarter angle. His face must remain highly consistent. Preserve his strong masculine jawline, defined cheekbones, thick dark eyebrows, dark expressive eyes, straight nose, natural lips, short black hair and clean natural skin. Add small professional facial-description notes underneath.

SECTION 4 — EXPRESSION SHEET:
Create a 2-row grid of ten expressions using the exact same male identity: neutral, happy, smiling, playful, sad, surprised, thinking, confident, worried and calm. Expressions should change naturally while the face, hairstyle and facial proportions remain consistent. Use head-and-shoulder framing.

SECTION 5 — POSE AND BODY LANGUAGE:
Create six full-body photographs of the same male character wearing the same red tracksuit: standing confidently, walking naturally, sitting casually, relaxed pose, arms crossed confidently, and looking back over his shoulder. Maintain realistic anatomy and consistent clothing.

SECTION 6 — COSTUME DETAILS:
Create detailed macro close-ups of the outfit: white T-shirt neckline, red jacket collar, metallic zipper, sleeve and seam details, elastic waistband and drawstring, back jacket detail, red fabric texture, zipper hardware, T-shirt graphic area and white sneaker details. All costume details must match the original reference.

SECTION 7 — COLOR AND MATERIAL PALETTE:
At the bottom create a professional palette containing red, white, green, black and neutral gray/beige HEX color blocks. Beside the colors place realistic texture samples for red tracksuit fabric, white cotton T-shirt, zipper metal, ribbed cuffs, sneaker material and drawstring.

The final result must look like a high-end professional character/model reference sheet rather than a random collage. Use photorealistic rendering, realistic skin pores, accurate clothing folds, natural shadows, studio-quality lighting, sharp focus, clean typography, consistent scale and precise alignment. The same male character must appear in every panel. Do not change his identity, do not add a woman, do not alter the outfit design unnecessarily, and do not add any unrelated characters or objects.
