It's an interesting effect with the guy and the things coming off his back, almost like he is disintegrating but not really. It's very cool. The only thing that I noticed was the render and the background aren't blended together unless that was the thing you were looking for.

Something else I noticed. This bottom sig that you have with the guy and the aviator's. That is amazing. All I can say, it's a great sig as well. :P
