An anime / illustration prompt with a clear style reference.
Prompt
Transform the people in the photo into chibi-style 3D characters. The parents are dressed in Western wedding attire — the father in a formal suit, the mother in a wedding gown. The child is a beautiful flower girl holding a bouquet.
The background features a colorful floral arch.
The characters are in 3D chibi style, while the environment is photorealistic.
The entire scene is placed inside a photo frame.
It leans on a clear description of the subject and mood instead of camera jargon. That makes it a flexible base: add a focal length, a light direction and an aspect ratio and it will land the same way on every run.
