Lovely detail and execution but have to agree n the nid scheme. Also just to add, if the rhino is still smoking (ie running) they're should be some action from inside, maybe a nid being blasted back by the rear ramp opening, a dead gunner would have been nice too.
I do think that the buildings are wonderful, and whilst I get the mulitple tech levels of the imperium, it kinda feels like stallingrad or Berlin during WWII, with protagonists from the 41st century added.
But again as I've said lovely detail and execution, would like to see you do a wierd war scene.
