"input_requirement": {
"required_condition": "input image must contain a visible mouth or mouth-like opening",
"usage": "use the mouth position, face direction, and basic expression from the input image as the transformation anchor"
},
"transformation_goal": {
"main_goal": "turn the input subject into a cute vertical plush 3D mascot with an exaggerated happy tongue-out expression",
"identity_handling": "do not strictly preserve the original species or object form; reinterpret it as a playful toy-like character in the reference style",
"mouth_rule": "the detected mouth becomes the origin point of a large soft curved pink tongue sticking outward"
},
"character_design": {
"body_shape": "upright rounded capsule body, soft cylindrical silhouette, no visible arms or legs; the lower body must continue beyond the bottom edge of the image and must not show a complete rounded base",
"head_shape": "head and body merged into one simple vertical plush form",
"ears": "two large upright triangular ears placed asymmetrically but balanced, soft furry edges",
"eyes": "oversized glossy circular eyes with white rims, deep blue-purple glassy pupils, strong highlight reflections",
"nose": "small rounded dark blue or navy nose centered above the mouth",
"mouth": "small smiling open mouth, simplified cartoon shape, friendly and joyful",
"tongue": "large exaggerated pink tongue, thick soft rubber-like form, curved downward and sideways, attached naturally to the mouth",
"fur_pattern": "white main body with warm brown patches around ears, forehead, and eye areas",
"surface_material": "short plush fur, soft tactile texture, subtle fiber detail, toy-like 3D material"

"visual_style": {
"style_name": "cute 3D plush mascot render",
"aesthetic": "playful, soft, child-friendly, toy-like, clean, polished, high-end character IP design",
"render_quality": "high quality 3D render, smooth geometry, soft global illumination, subtle subsurface scattering, detailed plush fibers",
"mood": "happy, silly, energetic, lovable"
},
"composition": {
"framing": "single centered character, upper-body close-up, hero visual composition; crop the lower body out of frame so the mascot appears to extend below the screen",
"camera_angle": "front-facing with slight upward or playful head tilt",
"scale": "character fills the central vertical area from ears to chest, with generous side and top breathing room; bottom edge cuts through the torso, never showing the full lower body",
"background": "clean warm yellow to orange gradient background with soft vignette",
"depth": "minimal background depth, focus entirely on the mascot",
"bottom_crop_rule": "the lower half/body base must be outside the visible canvas; do not show the full capsule bottom, floor contact, feet, ground shadow, or a standing full-body silhouette"

"main_light": "large soft studio light from upper front-left",
"fill_light": "gentle warm fill light",
