Here is my first try with the 2.0 version of your hypernet using a portrait of Alexander II as the img2img base, I painted the background of the original image black in photoshop:
Generated 100 images, about 40 were good enough (a very high percentage!), did some minor fix up and then batched em' through photoshop auto resize and smart sharpen on 50%.
Second row, fourth one is my favorite, such sad melancholic look. Some really look like gruff Russian naval officers, I really appreciate the fabulous mustaches.
The img2img generation probably needs some keywords to improve the intensity of the lighting, it did generate all pictures with a perfect black background, so might be a good way to save time.
The coat is a little overly greebly, maybe my image size is set too high?
Here are the settings:
Spoiler
Russian officer with a mustache wearing a peaked cap, black background, starsectorportrait, sabattier effect
Steps: 40, Sampler: DPM2 a, CFG scale: 7, Size: 704x704, Denoising strength: 0.75, Mask blur: 4
I first tried your sample prompt from readme and I think your current version might be tad over trained as it really did not want to give me a balaclava.
