A dim tunnel full of graffiti is a great place to find inspiration for your next perfect portrait.

Technical notes

  • I intended to get a full body realistic portrait. The keywords photo portrait and the portrait image size (512×704) helped. The keyword skirt and stocking helped to make the legs visible.
  • Perhaps due to the keyword tunnel, the initial prompt generated a subject too far away. Close up keyword made it too close, making the tunnel not visible. Finally I found the right balance with the keyword cover.
  • It was hopeless to generate a good face with that small face size. All faces were fixed with a second inpainting step.
  • To finely control the look of my model, I used keyword blending to mix two faces. I chose Liza Soberano for an asian look, and blend with Emma Watson to make the facial feature sharper.
  • Keyword stocking is used to make the lower body more interesting.

Inpainting settings

You will get pretty bad faces because Stable Diffusion is not good at generating small faces.

Inpaint with original prompt and model. The important parameters are

  • Mask: The face only
  • Prompt: (same as original)
  • Mask content: Original
  • Inpaint at full resolution

but with full resolution on and face restoration.

Below is a screenshot of the full setting.
