There is my new sig )

I'm not a fan of red and green together, it always looks like Christmas to me. I think it needs some lighting right behind the text too.

Nice background, the guy needs some smudging. Personally I would get rid of the current render and search for a new one, one thats fits in better.

I think you need to blend him into the background, use a few effects, and it will look nice. Also, try moving him off to the side a little, one figure sitting in the middle of the tag just doesn't look appealing. One more thing, lol, sorry. Use some gradient maps and blend the colors of him and the bg together. Then it'll look tight.
