It looks like he cant move an inch! I think this design isnt working. The only thing that can cause chaos is propably his gun and defenitely his movement.
Funny, since this is the last frame of an animation I did for him. It also seems you are not familiar with Warhammer 40K.
so much detail and effort and work and dirt and rust put into everything except the skulls. they look like shiny new plastic. amazing work. that shoulder crunched into a skull is really interesting
