On the second, his right arm looks off, because if his fist is supposed to be facing towards us, then I think his arm would be closer to his body (I can't think of how to explain and I tried to edit which didn't work), and his elbow should be pointing almost straight back.
Erm, if that makes any sense, that's what I think. If not, I'll try to edit it again.

Well, it's just that, although it may not be intended to be hysterically funny, it just doesn't make sense. It needs to be somewhat understandable to be funny at all. "You're pissed aren't you?" is just random and doesn't at all pertain to the actual thing...just something to keep in mind. And you forgot a comma after "pissed" (I'm sorry, but I a grammar freak  )

Heh, Indigo, that's pretty 
What's zbrush, though?

Wow, he wasn't accusing you, just making sure. You're sounding awfully defensive (just kidding...it's a joke...ha). The sprites are very good, just fix the balance. And you have to admit that it is just a tad suspicious (not accusing you of anything  ) that you asked him to do it with the rest of your sprites.
