The character render looks a bit odd in the heat-wave-ish setting of the rest of the picture, because the most evident colour scheme used on him is cold whereas the rest is blisteringly hot. Cleaning up the edges of the render wouldn't hurt either, especially on the hair.
Other than that, it looks pretty cool. Looking at it on my iPod this morning I was wondering why it was so wavy (it only shows animations on certain pages, apparently, so I only saw one still), and then I logged on here and went "Oh, damn."
THEY TOLD ME I COULD BE ANYTHING SO I BECAME A SIGNATURE PLS HLP
