I don't know much more there is to say about these guys. The weapons are mostly gunmetal drybrushed with steel. The big ape's tubing are drybrushed with a pale green over an olive base. I spent a little time detailing the backpack, because I thought it would look a little better if there were more colors to pick out the various shapes.
Peter Dell'Orto painted up his apes in a different scheme, and I'm just amazed at how different it makes them look.
