Not bad mine are better but you know haha my favorite is rainbow because of the many different colors
My favorite is escape cause it has all the colors but you can still see the spartan well. but they are all pretty good
Light & Dark does little for me. It's well put together but the background and light gradient just seem bland in comparison to the starkly detailed spartan. I like Escape a little more, the colours are nice even if it isn't something new, but again the definition on some of the spartan's armour, specifically his right shoulder and chest, kinda grate with the smooth flowing tone of the rest of the pic. But I really, really like Rainbow. It's a really nice use of the uber-colour technique, and the gradient of colours across it is beautiful. The stark diagonal line extending in to the right of the image really picks up the flow perfectly and continues the detail in to the right half so that the 2 sides of the pic don't look unbalanced. And the climactic direction shift of flow from the central white bar in to the detail on the left hand side is spot on. Sorry I didn't have quite so nice things to say about the other 2, but I really like the Rainbow one, nice work. EDIT: Lols, I just looked a bit harder at the Rainbow pic, with a Halo-eye instead of an "Ooooh, perdy" one, and figured out that the diagonal line is a Sniper barrel and the detail on the left is Spartan armour, I fail . But still, it's a nice thing to be able to say about a Halo screenshot, that it can be appreciated simply as something that's pretty to look at, and doesn't scream MC at you.
It would have to be the second one Although I can't really see a spartan. And I don't really think that scout is the best armour pic for a screenshot.
