Hawk: please, for all that is holy, ditch that beastly superiority complex of yours. Also, please stop posting that same mediocre work as an example. Instead, find a better sprite to give him an example of, but ALSO be sure to point out exactly why that sprite is better. Telling someone to basically emulate another sprite will never help. Tell them what's wrong, what they can improve, and tips on how to do so. Maybe even edit it to help illustrate your point. If you can't even do that, then maybe you should work on improving your own work, instead of sort-of trying to help others.
Dyuaru: I rather like the side view. I think that in the front view, however, you shouldn't have him twisting from side to side as he walks. It'd make more sense if he was running, but he really should have much side-to-side movement when walking. His body (and head) should be facing forwards all the time.
