I'm sorry, but that "bullet"'s lack of streamline form makes it a terrible projectile to fire from any kind of gun. And I think a line of awesome can be drawn from his right deltoid to his left serratus (excluding the "bullet").
Weird question: if I linked back to this image on dA, would it be okay for me to use this image as a possible image on the biography page of a character that I have at www.lotgd.net? "Steampunk Cat" is a good explanation of that character.
