Selfie-to-cartoon style split-screen mockup

Objective: To create a vertical, app-style promotional mockup for a "selfie-to-cartoon" image conversion tool, showcasing how the same portrait can be transformed into various cartoon styles while maintaining facial structure recognizability. Canvas: A 4:5 aspect ratio similar to smartphones, with a dark, glossy interface border and thin, cyan glowing lines along the left and right edges. The background is softly blurred, resembling a desk or a creative studio environment with paper and drawing materials. Layout: The main preview image occupies most of the screen, precisely divided into four vertical style panels from left to right: 1) Realistic selfie/photo style, 2) Black and white cartoon ink painting style, 3) High-saturation retro comic strip halftone style, 4) Blocky pixel art portrait style. A large, centered square mask/placeholder covers the middle and upper body area in a warm beige-gray, as if the central facial area is deliberately hidden. Below the main preview image is a dark carousel containing four rounded thumbnail cards corresponding to the four styles: selfie, cartoon ink, retro comic strip, and pixel art. Main details: Featuring a young woman,{argument name="hair color" default="Dark brown/black"} The character's messy hair is tied into a high bun, with eyebrows and eyes visible on both panels. They have a medium warm skin tone, wear a simple dark crew neck shirt, and a thin necklace. Maintain the same head position in all four transformations. Style Panel Details: The Photo panel should look like a casual indoor selfie with shallow depth of field and a natural texture. The Cartoon panel should use dramatic black ink, white highlights, crosshairs, and clean lines. The Retro Comic Strip panel should use bold outlines, a red-yellow background burst effect, blue-black hair highlights, orange skin tones, and halftone dots. The Pixel Art panel should use large square pixels, simplified facial features, a cyan background, and a limited color palette. Visual Style: High-contrast social media product preview, clean vertical division, glossy black UI shell, neon cyan accents, simple rounded-corner thumbnail cards, and sophisticated GPT imagery aesthetics. Constraints: Include 4 precise main vertical panels and 4 bottom thumbnails. Do not add readable text, logos, or watermarks. Keep the central beige square mask prominent and perfectly centered.{argument name="interface mood" default="Dark futuristic mobile UI"} ,{argument name="comic transformation theme" default="Comic strip, retro comic strip, and pixel art selfie conversion"} as well as{argument name="background setting" default="Blurry creative studio desk"} .
