Like tidoco2222 was saying it needs some blood. And his are carrying the gun looks to stiff, you need to make it so he's droping the gun with his hand open. other then that Great mini! like the converiton!
This is a nice looking mini I like the way your metallics turned out, the only real problem here is the Space Wolf victim.
There are no shades or highlights on the armour and also some pretty serious mould lines there. Also where is all the blood I mean lets face it the poor guy has had his head ripped form his shoulders so there should be plenty of clarat about.
