Cartoon Sticker Transformation Prompt

Transform only the main human subject into a cute full-body flat 2D cartoon, preserving their hairstyle, glasses/accessories, facial identity, outfit, colors, pose, and props. Remove the realistic person completely. Keep the original photographic background 100% unchanged no stylization, redraw, simplification, or color changes. Add a thick white sticker outline around the cartoon and a few subtle sparkles/doodles. Use clean modern flat colors, rounded proportions, minimal facial features, soft pastel tones, and cheerful expression. No anime, 3D, realistic human, extra characters, text, watermark, or logo.
