if you want to do this yourself you're going to want stable diffusion and one of the clipspace face embedding controlnets (tencent Photomaker is one), the ones that keep the input pose exactly are likely using depth as well or maybe straight image2image, I demoed something like this at open sauce this weekend making pixel art on an ancient dot matrix printer.

I'll endeavor to package everything up and post a repo in the near future, this sort of low effort sass stuff really irritates me. I'll do my best to replicate this functionality in a easy to use open source UI/UX
