Gears of War 3: Wallpaper Design Contest

I came across a contest on DeviantArt by chance from my return from California. The prizes are too good to pass up, not to do it! Theres something like, four days left. The entries must be in by September 28th. Check it out HERE. I dont want to post the final piece till its completely finished and posted, So I will post the thumbnail that I chose to elaborate on.
