(Last I read, training the models on specific image sets requires an industrial grade GPU--something closer to an A100 than a 3090--which isn't something I have access to.)
Would love to know more about what kind of prompts you worked out to get the style so closely, I really struggled with managing that so instead I have been spending my last few weeks working on training models to use for my starsector mod making since I couldn't ever seem to manage decent results with just prompts alone.
I was planning to work on a portrait pack myself to go along with releasing the portrait model I have been training, but looks like a bunch of you have all beat me to it for AI generated portrait packs. Though I have been spending all my time trying to improve and train a better and better model so I haven't really stopped to make use of it yet even though the results are probably more than good enough.
I will make a full forum post when I finish up and release the model, with some tips and guides on things I have learned while using it.
This is a batch of images directly out of the custom model I have trained, I have thousands more of similar quality just sitting around now.
The model is able to adapt quite well and will maintain the style even if its generating things well outside the scope of the training set. I posted a bunch more under the spoiler with some outlandish things that don't exist. Obviously some images still have issues not everything could be used directly out of generation but so much of it is just a few steps from usable.

The only editing I did to these was chop out the backdrops to make them black
Some of this stuff is not supposed to exist you have been warned!
Spoiler
These I haven't edited at all and are directly from generation, you can see that sometimes it gets the black background correct but frequently it fills it in, but overall it holds the style very well even on subjects well outside any of the training data.
If anyone wants any more info just contact me I am the same name on the unofficial starsector discord
