I saw your animation and I think it is good, the character moves nice, but you could improve the flow of the movement, specially the initial sequence. What I think needs to be improved is the modeling, texturing, and above all the lighting and rendering. Those aspects, in my opinion, could be better. You should try radiosity or global illumination, and also the scene needs more light. You should also try to polish your figures and character. But again, I liked the animation of the character, keep up the good work!!
