Except I didn't take your wallpaper and after simply putting 'MW3 wallpaper' in google images I found several similar to yours so how do I know that's even your original work? Now kindly leave this alone, all replies to you will be in the form of 'trololololololol'
erm...not sure what 'watermark' you are talking about as i can not see one on mine, probably because i got the 'Call of Duty' part as a separate render. I am unsure of what the link is showing me other than that you use far too many layers and are quite disorganized. Try using 'Ctrl+alt+shift+E' once in a while maybe? Anyway, i digress, back to the matter in hand, trololololololol
Since the Russians are attacking New York City in the game, and I'm going to go there on vacation in a few days, if those Russians destroy the Empire State Building, Chrysler Building or the Statue of Liberty I'm gonna say YOU RUSSIAN MANIACS! YOU BLEW IT UP!
