I always ask for revs or checking for errors. Anatomy, compositions, colours... bro We are human artist, we make errors and grow from them. As long as the changes are reasonable and not changing the whole pose from the agreement. It's good! also read TOS for the limit of rev 😉
Guys I have a question that's itching at the back of my mind for some times...
If I commission you, and I correct your anatomy, would you be ok with that? O.o
