I swear my art only looks decent if I put 5 hours into it, my linart is slanted af unless I keep altering it while flipping the canvas, most of my ocs are awkward and difficult to draw, I can't find my artstyle, I do not know how to apply color theory or composition.

I don't think my art is particularly bad or anything, I don't need reassuring, but, if you have any advice, and I mean any, even if you're unsure if it'll be good advice or not, give it to me because I'm desperate for solutions lol
