As I'm new to this forum, I don't really know how critics are received. Please, take mine as a try to be constructive. Btw, It's a bit hard to do a good critic with such a small sprite size, but I'll try to do it anyway :wink:. It seems that you tend to animate just the legs of your sprites. Please, give some love to the upper part of the body too! For example, you could make the ninja arms do a small, subtle bounce as he walks. I think that you can really give a push to your work with little effort, you already do the hardest part.
