It's not that it mores quicker, it's that it moves MORE - the left arm doesn't swing past the front or back of the torso but the right arm does. I'd suggest changing it so that they move the same distance.
I would also say that the "bob" that occurs when he is walking is slightly off - you appear to have one "bob" per step, whereas you should have two - the body is elevated slightly when each of the legs is fully vertical. Right now it looks like he has a bit of a limp.
I like the character though and think that it could make an interesting style graphically - as long as all the characters and backgrounds (and art in general) were consistent.
