"Who will be the last standing"?

Well, such s long time I'm not been here, a lot of homeworks and exercises as usual, althought they're not related to CG but it still sharpen my skill anyway. (I didn't realize it before I paint this piece).
I don't have enough time so I combine matte painting skill with concept art.
So, I hope you will enjoy it, and, of causes, your crisis is a critical matter. Without you I cannot be, so welcome any c&c.
