This style has been trained on 50 Midjourney head and shoulders portraits of old women in steampunk style. It can produce young women, but men very hard.

Recommended settings:

Canvas: 512x512 with high res fix at 1.5 or 2.0 upscale

Models: realistic (Deliberate, AnalogMadness) or Midjourney family (Dreamshaper, Dreamlike Diffusion, Protogen family etc). Anime models perform well.
