Finished? but not happy...

I have animated what I can, but it's getting to that stage where I need to stick with my 3D animation now and leave my 2D behind. I'm not happy with it their are some parts which I do not like. I think the walk cycle is ok but the last scene is really bad and I am not happy with it. My teacher says that i have to concentrate on my 3D animation now and if I have time I can go back and polish it up and make it look more nice. so fingers crossed that this is not the end peice and I will upload something that looks better than this. :)  
This is my piece.
