Based on the uploaded portrait photo, generate a "retro flat dimensional character design sheet".

Character name: {{enter a name or nickname}}

Transform the real person in the photo into a reusable personal IP character and present it as a vertical character design board. Use a retro flat dimensional illustration style: mostly flat, slightly dimensional, low detail, low saturation, soft shadows, matte texture, subtle vintage grain, light beige or warm white background, clean layout, generous whitespace, like a professional character design manual page.

Use the uploaded photo as the only reference. Preserve the most recognizable features, including face shape, facial proportions, eye expression, eyebrows, nose, lips, hairstyle, hairline, apparent age, skin tone, body silhouette, and overall temperament. Express it as a flat character translation, not realistic, not anime, not designer toy style, not overly cute, and not a big-headed doll.

Reference the clothing from the original photo and simplify it appropriately into a fixed character outfit suitable for long-term use. The outfit should be simple, everyday, recognizable, with fewer complex folds and realistic fabric textures, and no unrelated brand logos or extra accessories.

Fixed layout:
1. Center "{{enter a name or nickname}}" at the top
2. Under the title, write "Character Design" in small text
3. Place the largest full-body main character in the upper middle, standing naturally on a simple circular base
4. Arrange four small character views horizontally at the bottom, in this order:
Front / FRONT
Left side / LEFT SIDE
Back / BACK
Right side / RIGHT SIDE

All four views must stay completely consistent: the same hairstyle, face shape, outfit, shoes, accessories, colors, and body proportions.

No left-side accessory area, no color palette area, no character bio, no personality description, no long paragraphs, no extra English, no garbled text, and no complex scene.

The final output should be a clear, orderly, reusable personal IP character design sheet in a 3:4 or 4:5 ratio.
