What to Change First

  • Change the subject block first: { "image_description": "A striking, modern fashion advertisement.
  • Adjust the mood through light and backdrop cues: ", "background": "Clean, solid blue gradient background (medium to dark blue).
  • Keep the finish constraints aligned while you test variants: " }, "graphics_and_text": { "text_elements": [ { "content": "S", "style": "Large, bold, sans-serif, white...

Before You Generate

Note 1

Start with a sharp reference image. This prompt is written to preserve source identity, silhouette, or product structure before stylization.

Note 2

Use 3:4 on the first run, then test alternate crops after the base composition is working.

Note 3

This prompt suppresses text or logos. Remove that constraint before asking for branded packaging, typography, or visible watermarks.

Best For

  • Portrait studies, beauty concepts, and tightly framed editorial references.
  • Reference-image workflows where identity, product shape, or silhouette should survive the restyle.
  • Clean studio results where spacing, surfaces, and product separation need to read immediately.

Skip This Prompt If

  • You need a wide environment shot or multiple subjects competing for attention in the same frame.
  • You need to begin with a radically different crop than 3:4 instead of honoring the existing composition hints.
  • Your reference image is low-resolution, badly lit, or cluttered enough to break subject preservation.

Mistakes to Avoid

  • Ignoring the recommended 3:4 crop on the first run. The prompt's composition cues were written for that frame.
  • Using a muddy reference image and expecting the prompt to repair identity, silhouette, or packaging structure on its own.
  • Asking for readable type, logos, or packaging text without first removing the no-text constraint.

3 Ways to Adapt This Prompt

Use these as safe starting edits so you keep the prompt's structure while still making it your own.

Swap the subject, keep the frame

Replace { "image_description": "a striking, modern fashion advertisement. with your own subject while leaving the camera and composition cues intact.

Retune the mood, not the structure

Keep the subject block, then rewrite ", "background": "clean, solid blue gradient background (medium to dark blue). to move the image into a new lighting setup.

Push the restyle with a cleaner reference

Start from a sharper or more contrasty source image, then edit finish descriptors only after subject preservation is stable.
