It's been day and I want to stat painting it, but I dont know if I'd ruin it or not somehow.
I would...it sucks, I know, but you want to make sure your sculpture will withstand time, and wet plaster gets weak....
If it's not fully dry, the paint will lock in moisture that will eventually cause your sculpture to crack and crumble.
So I should wait another day? :(
UGH, i'll make myself wait.
