Read this entire thing before you get angry. The art work first off would be kinda cool if you were trying to make it look bad like that. I'm not saying you suck at drawing I'm trying to say a lot of it looks like real drawing with traced backgrounds. The frame by frame looks okay for a beginner but a lot more frames should go into making the animation. I would really try practing drawings of calvin and hobbes until you get something your comfortable without having to take to much refrence to draw. I would also suggest not tweening noticable things like hobbes face. I this makes you angry then just igonre it.
