The legs of the main character are looking incredibly awkward, since they are spread apart so widely. The frame where he's preparing his attack more looks like he's dodging, but meh, it's alright, I guess.
Something's not right with the face or the hair of the furry character. The hair is forming a sharp corner on top of the head.
I'm seriously, the legs of the main character are looking silly, even funny! :D Even in his default, unanimated pose.
The rest is pretty, no mistakes noticed.
But wait! There's an animation of the last character at the bottom. On the second frame he seems to have shifted his weight to his right leg (HIS right leg), although the knee of it is not beneath the body, which is incorrect and, indeed, more looks like he's jumping in the air than standing.
If you are tired - I understand that perfectly - let me do the animation job for you! Ha-ha-ha! This is going to be amazing.
