/ic/ - Artwork/Critique

This one sketch took me two hours. Just this. I feel like a retard wasting time because my whole process is just hitting undo undo undo until the line finally looks right or until I give up, but then once the whole thing is done and the pieces fit together they look wrong anyways.

Back in high school I took a beginner drawing course for teens; part of that was 1-minute gesture drawings, and I absolutely sucked shit at them because I could NOT live with a line that I knew was wrong. How the hell do I get past this? Feels even shittier because I know something like this should have only taken like, 10-15 minutes at most, but everything I attempt is like this. Thanks for reading my blog.
