Very cool looking, sorta like some Neo-Stargate stuff. The lower half seems to be lacking in detail compared to the upper half, it may look a bit cooler if you got your friend to add in some more armor on the legs.

looks cool, now make him dirty! His skin looks way too soft and smoth, give him some grit.

The tatoo though..... something a lil more of a african or maybe a off beat toltec design?
