Could be Alistair from Dragon Age. If there was a movie, this would make a great poster for it!
I love the dusty feel to it, I imagine howling wind when I look at it. Excellent detail on the armor too, it looks worn, so this is a warrior rather just a pretty face in shiny armor, if you know what I'm saying : D .
So, as usual, as others have said it before me: Masterpiece.
Also, just noticed: Is he holding some kind of necklace or talisman in his hand, or is it a handful of sand trickling from his fist?
