Somethings putting me off about this but i can't really tell what, maybe an outside perspective could help

You might want to fix the positioning of the limbs. look into "fore shortening". As the legs sway back it should get smaller and should be a "slightly" dark shade,same with the arms. Don't be afraid to move the arms more as well. And it's a walk state so you might want to increase the delay within the frames.
