Something fun to do if anyone's interested. It take any portrait image and creates an old painting from them. There is an app version with more features but the browser version is pretty decent on it's own. https://www.portraitai.app/ I will say this as fair warning; don't post anything you know you shouldn't. If you're concern about privacy, then don't do it at all. If you want to try to use lewd, crop just the head. 1:1 Head crops have better results anyways. When passing stylize characters, there will be times you'll get hilarious results. So for honest results, you should use Photoshop, Gimp, etc to make tweaks before passing it through. Tweaks such as: -Warping the eyes smaller if characters have huge eyes. -Eyelashes are sometime mistaken for eyebrows, so tone down the lashes. -Warp circular heads to a make realistic shape. Your tweaks does not have to be a masterpiece by any means, just enough for the AI to use to help it's conversion.

His colored sketches dont translate well and unfortunately only releases these instead of sketches. However the colored works have improved over time.
