I don't know what the use case is for other people is, but I've been playing around with book covers. This one took about two weeks, but it was my first real try and I was still learning how. Composition is a little off. The one I'm working on now is going faster (and better).
I've found that I rarely get a usable image completely as-is. It might take 5 or 10 generations to find something sort of ok, and even then I end up erasing the bad parts and letting it in-paint (which again takes multiple attempts). The T-rex had like 7 legs and two jaws, but was otherwise close to what I wanted... just keep erasing extra body parts until the in-painter finally takes a hint.
I was also going to do a few book covers for some Babylon 5 books, but it does so bad on celebrity faces. Looked like Koenig's mutant love child with Ernest Borgnine. Dunno what to do about that. I keep wondering if I shouldn't spend the next 10 years putting together my own training set of fantasy and science fiction art.
