What you whould ad is bounce, making him look like he is really jumping of the ground and landing with some weight. depending on what kind of runing your aiming for.
Now he looks like he is kind of runing like a springet, very stif upper body and no movement up and down. I really think it would look beter if he were to run more heavy.Allso you should ad some rotation on the hips and the shoulderparts.

pretty good except you need something moving on the upper body, do you run with your upper body stiff?

that face doesn't look like a face... maybe a bit more detail on it?

Why is he limping?

Wpytke ziomus ,wpytke:D zgodze sie z pozostalymi ze gorna czesc bez animacji wyglada jak krokodyle lajno,no ale co poradzic. Niech zgadne-postac bedzie mogla celowac w rozne kierunki ? Ogolnie jestem pod wrazeniem:) :*

his head is a tad bit small. there could be more vertical bob as well.

i agree about the animation, it's weird without any upper body movement..
solid pixeling though.

Pretty big problem.  It'd look much better with head/sholder/arm movement, but if this is all your restrictions allow, I'd say you did a good job.

Really i'm not allowed to animated arms (problem with the game code).

Thx for comments ;)

Shouldn't the upper torso move?

Nice shading and overall nice job.

Not bad, but if you already put such detail into animating the legs why not the rest of him. (Arms mainly.)

I like it.
