使用提供的参考图作为主要身份和姿势参考。将人物转换为一幅可爱、俏皮的手绘涂鸦插画，同时保留其可辨识的身份特征。

Use the provided reference image as the main identity and pose reference. Transform the person into a cute, playful, hand-drawn doodle illustration while preserving their recognizable identity.

STYLE:
- Adorable handmade sketchbook doodle aesthetic
- Simple black pen/pencil line art with slightly rough, imperfect strokes
- Childlike, charming, whimsical drawing style
- Minimal coloring with soft pastel accents
- White/off-white paper background
- Visible hand-drawn texture and natural sketch imperfections
- Avoid polished digital vector art or overly clean anime rendering

CHARACTER:
- Preserve the person's key facial features, face shape, hairstyle, hair length, clothing, accessories, and overall appearance from the reference
- Keep the person's recognizable characteristics rather than making them look like a generic character
- Use simplified cute proportions with a slightly oversized head and expressive eyes
- Large round hand-drawn eyes, tiny nose, small cheerful mouth, and subtle blush on the cheeks
- Keep the original hairstyle recognizable while translating it into loose sketchy strokes

POSE & EXPRESSION:
- Preserve the main pose and body direction from the reference
- Give the character a cute, cheerful, playful expression
- Natural hand gestures and expressive body language
- Add small doodle elements around the character that match the mood, such as hearts, stars, crowns, sparkles, motion lines, flowers, or tiny symbols

DRAWING DETAILS:
- Black sketch lines should be slightly uneven, textured, and imperfect
- Use loose cross-hatching and scribbled shading where appropriate
- Pastel pink, yellow, blue, or other soft colors may be used sparingly for cheeks and decorative doodles
- Keep the illustration mostly monochrome with selective colorful accents
- White background with plenty of negative space
- Make it feel like someone personally drew the character with a black marker or pencil on paper

COMPOSITION:
- Center the character prominently
- Keep the framing similar to the reference photo
- Add a few cute surrounding doodles without distracting from the character
- Clean, simple composition suitable for a profile picture, sticker, social media post, or cute illustration

IMPORTANT:
Do not make the character photorealistic. Do not make it overly polished, 3D, glossy, or professionally vectorized. The final result should look like an authentic cute handmade doodle drawn by a talented person in a sketchbook, while still clearly resembling the person in the reference image.
