Why so strange? Stranger doesn't mean better.

Anurag Sahu:

nice act but its looking flat ....it can be much better :)

Owen:

Like the exaggerated postures. Would like to see the situation he is yelling at for greater context and emotional import.

Danny Kneip:

The best way to avoid animating a lip sync is by covering or hiding the face - which you've done with ease here. Unfortunately, it's not much of an animation.

Damián Navarro Méndez:

without mouth and facial expression you won't improve. Also the walk is wrong... don't be afraid of animating mouths
