Looks good, but there is one detail I'd like to point out that I thought was very nice! (whether intentional or not) The deviantART watermark that shows seems to be part of the entire piece. (well, except that last 'm')
I love surreal illustrations like this. These days, an image like this resonates with a whole lot of peopl - and to say nothing of the message, the preciseness of the lighting and composition are impressive.
