I'm so lost rn. I have been painting digitally for +3 years. I have the feeling that I have past the beg tier, and I was starting to get somewhat confident with my level. Yet I can't never EVER finish shit. There's something bugging me, there's something that could be better, an edge to correct, a small spot in the wrong layer, something to render that I'm not quite sure how to. That's how I have spent like two months, trying to finish things or details, that are completely invisible to my friends/peers but to me they look like huge crap. I've been working for like 2 months only in three pieces, yet I can't bring myself to say they're finished. Im slow af with corrections, but I simply don't know how to be faster... Any advice with this? Should I sign up on psychologist therapy to stop being a coward and just upload the goddamn thing and start working on something else? Any tips rendering tutorial courses available online, aside scott robertson and the ctrl paint site? Anything is going to be fine. pls
