Cosmic Galaxy Watercolor Portrait (Identity Preservation)

{
  "prompt": "Use the uploaded reference image to **preserve 100% of the facial features, identity, age, skin tone, and expression** of the person. Do not alter facial structure or proportions. Create a **cosmic galaxy watercolor portrait** where the face remains soft and realistic but is gently merged with nebula textures. Hair follows the exact reference style, with subtle stardust highlights woven through the strands. Clothing: simple dark or neutral attire that fades into swirling galaxy patterns. Background: deep space filled with vibrant nebulas, glowing stars, floating light particles, and watercolor galaxies in shades of indigo, teal, violet, and cosmic blue. Soft ethereal rim light outlines the silhouette. Fine pencil sketch lines mixed with watercolor bleeds, smooth gradients, dreamy depth, cinematic and artistic masterpiece quality.",
