Think I have to agree with IJ. Your army is spot on fantastic (and I cant model worth anything so take this as you will...) but the positioning of the torso just feels...I dunno, off.
I know! it feels to me like he's getting ready to lean backwards into a matrix style bullet time scene....and that would be AWESOME if you could model that!
...maybe its just the lack of the other arm.
*shrug*
loving your army though.
