the images are in the file structure of the javascript version on windows as raw assets. you can find them there. the bust images are generally fairly low resolution (although I haven't specifically looked at sophora's). If you ask me nicely, I will re-render them using an AI up-scaler for you, but that is problematic as far as altering someone else's work for distribution, as it is technically altering the image. however minor the alterations, it'll be your job to hunt down the artist and ask for explicit permission before I consider doing anything of the sort, and don't be surprised if you get a resounding no. You'll also need to ask for permission from the tits team, as i'm fuzzy on the ownership/allowed use paradigm of the assets. Best I can personally do.
