Expect my original art to be licensed as CC-BY-NC-SA. More restrictions apply when there's copyrighted content in there. Redistribution of my art must be credited and associated with their original sources, and modifications or versions of my art's project files must be publicly available.
Q: Do you accept lewd or fetish art of your characters?
A: I only use a stock license instead of my own, and what I don't find acceptable could easily contradict what that license allows, and I often don't keep track of what I don't like. The license takes priority over my personal preferences unless it's personal harassment. Because of the "NC" part of the license, derivatives or alt versions of my art should never be behind any paywall.
Q: Use your art to train AI?
A: My works either don't use original assets or are of a bad or MS Paint kind of quality, which could easily dumb down art generators. What I allow is what the CC-BY-NC-SA license allows.
