It looks good, however the render has some problems. It is a bit low quality and the face is smothered with flame. However that isn't the main problem. The big problem with this wallpaper is the colour scheme. Blue and Orange/Yellow/Brown just don't blend well. In my opinion a good piece of work needs to have one primary colour scheme that is consistent throughout. Of course that is not always the case, I mean, i have seen pieces of work with all kinds of colours that look great. But if you want to blend something into another with pin point accuracy. A primary consistent colour is always the way to go. If your experimenting with effects sure go crazy on the colours. Sometimes it works, sometimes it doesn't. It depends on your style. Someone like Fear_09 is terrific with using colours and effects. His latest siggy has all kinds of colours and it looks great. But some other people prefer to have a primary colour as the highway.
Anyway back to the wallpaper. The text could have done with some work, your last few pieces of work you have gone down a big hill with your text. Keep it simple, sure experiment but remember. The best text is always done with a simple font, it may look exaggerated in some cases but that is only because maybe sometimes the person has added effects to the text. Don't go overboard with it man. Your doing well, the background is amazing.
