Quick edit to show how I'd change some things.
I'm not amazing with anatomy on small characters, but it seems like it's almost a crouching position. I've played a lot of the 2D metroid games, and your sprite looks remarkably like that (which sounds like what you're going for). However, I never liked how samus always looked like she was an umpire or was doing squats.
I tried to make him lean forward a bit more, and straightened his legs. and clean up some of the other things for clarity. It's really rough, but hopefully you get what I was going for.
Also, it seemed like his arms were a bit too long considering how small his body is.
EDIT:


edit to fix stubby legs and balance.
Love the greebles and detail, however. Sorry I killed those with my edit
