Yeah the lines look jagged, and I don't think Egaki's original lines look that way. I'm not sure what you did that made the line art look that way, but you should figure out why it happened, and try to avoid doing it the next time around. I'm not sure what you need to do, to make a breakthrough, and start to improve, but you should start to make a better effort in making your colorings look better. It's okay to get a little bit mad at yourself, if it helps you improve. You should raise your standards, is what I guess I'm trying to say. Well, I hope you do better next time around Madara, and it wouldn't hurt to follow some of the advice from the others.
