The first 3 are amazing, pretty much just because I don't like forge art. I saw the second one on my DSi first, so it reminded me of Master Chief looking over a table at Cortana. Just the way he's posed. the fifth one is a great Idea. The fourth one is just I don't know. =P
Decepticon fan I see? I like the first one, I like how the focus is dark but with a brighter background, pretty sweet dude.
