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 9:16 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

  • Celebrity-look transformations with high facial fidelity.
  • High-detail selfie edits that need a recognizable beauty reference.
  • Identity-preserving portrait restyles for social or editorial use.

Skip This Prompt If

  • You need a wide environment scene or multi-subject narrative instead of one controlled focal face.
  • You plan to change crop, subject identity, and lighting direction in the same pass.
  • You need typography, packaging, or heavy graphic overlays before the portrait frame is stable.

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 { "subject": { "identity": { "biometric_reference": "sydney sweeney", "analysis":... with your own subject while leaving the camera and composition cues intact.

Retune the mood, not the structure

Keep the subject block, then rewrite ", "neon_sign": "small-scale custom neon sign 'pinodi' in an elegant cursive font,... 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.
