FIRST attempt at Walk Cycle

So, I've been forced to learn some character animation for a project I'm working on and I wanted to upload this to hopefully find some of you super talented folks out there to give me a little critique.

I know dribbble wasn't really designed to give critiques but please, any information is very helpful for me! I've gotta say I really though I didn't think I'd enjoy character animation but, it's kinda rewarding.
