基于自拍生成皮克斯风格头像贴纸

Using the uploaded selfie as strict face reference, keep identical facial features, hair, expression, and likeness. Create cute 3D Pixar-style avatar stickers: glossy 3D rendered cartoon character, soft lighting, depth with shadows, big sparkling eyes, chibi cute proportions, vibrant and fun. Generate multiple variations in one sheet - different poses, emotions like happy, cheeky wink, surprised - sticker format with clean edges and subtle border shadow, transparent background ready for use, high detail, 8K.
