good job on this character.
I think his pose is quite unstable though. He seems even howering a bit. Left leg doesnt seem as a solid support, and his torso which is leaning back makes me feel he'll fall back next second.
Moeover, his design suggests a calm and cold person (sigar, glasses, tophat), actuslly reminds Hitman to me

. Therefore in my oppinion a more calm and steady pose would suit him better.
He can still blow a smoke from his gun or have blod spatter around him anyways
