Well I am on an HD display... V2 the lighting is more pronounced, V1 it is more subtle. It's true there is still brown in v2, however the render is more black... I thought it looked better as a dirty brown. I just think the brown goes more with this considering he is in a jungle... if you've ever seen the original movie arnold covers himself in mud so the predator can't see em lol.
it's good either way, I still like v1 better though.
