Mockup de App con Retrato Dividido en Cómic

Vertical promotional app-style mockup for a selfie-to-comic image transformation tool, featuring a single portrait converted into multiple art styles while preserving facial structure. 4:5 composition showing a dark glossy smartphone interface frame with subtle cyan neon edge glows, set against a [blurred creative studio desk] background. The main preview screen is divided into exactly four vertical split panels from left to right: 1) a realistic indoor selfie with shallow depth of field, 2) a black-and-white manga ink illustration with crosshatching and clean lines, 3) a saturated retro comic book panel with bold ink outlines, halftone dot patterns, and warm tones, and 4) a chunky pixel-art avatar with large square pixels on a teal backdrop. A prominent warm beige-gray blank square mask covers the central facial region across all panels. Below the preview, a dark carousel features four rounded thumbnail cards corresponding to each style. The subject is a young woman with [dark brown/black] messy hair in a high bun, medium warm skin tone, wearing a simple dark crew-neck shirt and delicate necklace, maintaining the exact same head position across panels. Style: polished [dark futuristic mobile UI] mockup, high contrast, clean divisions, no readable text, logos, or watermarks.
