Looks nice, but a bit too dramatic movement for an idle pose. He's moving his arms like he's about to drop his pants. A more subtle arm movement would be better, I think.

What do you mean? This is pretty awesome.

The hair motion is pretty stiff though, and I'm not certain what he's really supposed to be doing, but it's a solid sprite for sure.

Would love to see some more of your work, keep posting!
