Ask HN: How do you deal with contracts that involve art?

Hey. I was debating a personal side project ( simple visual novel game ). I just want to tell a story, but I am not, for lack of a better term, talented when it comes to art so I am currently trying to commission some assets. That said, I am not entirely certain what to expect or what common pitfalls are. Are there any particular things I should keep in mind? Any phrases to cross out from contract? If you did it before, what would you have done differently?
