Well,I already gave you some tips and I even edited it for you.Anyway,one of your problems is the smoothness.You have to make your moves more smooth and fluid and make them look realistic,and your second problem is the pose.Most final poses are standing poses or something realistic but yours doesnt really look like a final pose.Anyway,I wont rate for now cuz it seems its not done yet.I will rate it when youll make a decent ending pose.
