/ic/ - Artwork/Critique

decided to do 50 boxes a day for the 250 box challenge, doing it digitally since that's what I'll be using anyway and I can practice my lines in warm-ups (or just use the line tool / shift click, no roolz only tools)

after I've finished drawabox should I move onto Ctrl+Paint?
I'm a little overwhelmed with everything I'll have to learn to make what I want; construction, perspective, composition, gesture, anatomy, rendering, light and color etc it never ends
even if I use stuff like references or 3d models I'm afraid of making a 'piece' since there's so many intricacies I know I'll fuck up, like drapery and anatomy and then how light will behave on it, I have no idea where to start with all of it
