The longer torso version totally works also. I just slightly preferred the shorter one, but I see what you mean about making him look like a kid. To me, both versions are completely acceptable and I was just nit-picking. And sorry to return any doubt to you about the animation

. I don't want to discourage you in any way, because your work thus far is looking great.
About the way he's holding the gun; I think as long as he isn't prepared to take steady aim to really shoot something, he's alright with walking with it from the hip. However, in my opinion, if he were to walk with it at the hip I would expect his arm to be a bit lower with his upper arm almost straight and the lower arm bent at about 90 degrees (like an L shape). I think that's just because of the way I interpret this character. That could just be me; it may look funky if you actually tried that.
Oh, and if you do decide to make him take aim in a more proper manner (IE: both hands on the grip with the pistola centered in front of the dominant eye) you might could use this as a reference. Just thought it might help

. Keep it up dude, it's going great!
