Hahahahahaha, I love his facial expression... even if he is a cat-loving dog-murderer.
Having said that, I do have some thoughts. Here, sitting at my computer, I can jab my elbow into my hip, and place my arm along my thigh to see how far along it extends. For me, my fingertips extend a little beyond my knee. For the cat-killer, it looks as if even his fingers wouldn't reach his kneecap. I'm not sure if that's because his forearm is too short or his thigh too long, but in either case something is wrong.
The only time I'd be able to stay upright in that position would be if I were springing up for a jump. That being said, I think it suits him, despite it seeming impossible.
Final note: I have no idea if it's supposed to line up, but if you were to draw a red line across the top of both shoulders, and one across the bottom of both pecs, you'd see that they don't line up at all. Just for kicks, put a nice blue line across both nipples and get a brand new line.
That's enough talking out my ass for one day, hopefully I said something valid.
