Prompt
Use the uploaded photo as the reference for the person. Preserve their recognisable face, natural skin tone, hairline and body proportions as closely as the model permits; check the result against the reference. Scene: a clean dark background; the person's head-and-shoulders silhouette is filled with a spiral galaxy with a golden core that fades out at the edges. Pose: side profile facing left, chin level, eyes open. Clothing: the outfit from the photo, mostly hidden inside the galaxy fill. Light: soft light on the face so the profile stays sharp and recognisable; stars glow inside the silhouette only. Style: artistic double-exposure photograph, crisp profile edge, fine star detail, natural skin texture on the visible face. Format: square 1:1 Avoid: covering the face with stars, changing the profile shape or identity, skin lightening, extra fingers, text, logos, watermarks.
Customise
For example: spiral galaxy with a golden core.
For example: facing left.

How to use it
- Open an external image tool listed above. The tested model, if any, is named in Status.
- Upload a clear reference photo of the subject. If it includes identifiable people, get their consent and check each face.
- Customise the fields, copy your version, paste it with the photo and generate.
- Compare the result with the reference. If a face, pose or detail changes, ask for one correction or try again; an exact match is not guaranteed.
How to use this prompt
- This prompt changes your own photo. Choose a clear reference photo, and get permission from people who can be identified.
- Upload the photo in the external AI app you chose. Fill Customise, press Copy prompt and paste the prompt with the photo.
- Compare the new picture with the original. Face, hands, clothes and pose can change. An exact likeness is not guaranteed.
Good to know
- The model may let stars spill across the face; ask for the face to stay clear and only the hair and shoulders to hold the galaxy.
- Use reference photos you have the right to use; get consent from identifiable people.
