So I've been reading your comic, and I really like it. But I noticed that on just about every page, you keep putting yourself down. Talking about how "bad" your art is. You need to stop that. You draw very well, yet you keep telling yourself you're no good. You have PAGES of people telling you how well you're doing, yet you don't seem inclined to believe them.
If your art isn't at the quality you want it to be, then don't stop drawing. If you stop drawing, then you will never get better and never reach that level you want to be at. The only way to improve your art, is to work on it.
Also, you shouldn't compare your art to others. I know it's hard, but try not to do that. Everybody has their own style, so comparing yours to someone else's isn't fair to you.
I just don't want you to give up on yourself. Okay? Keep trying.
You don't have to BE the best. You just have to DO your best.
