Very nice sig. Good depth, good text. I like the effects on his hand but I don't like the lighting, personally.
The depth in this sig is very good. The lighting seems a bit extreme to me, though... you should tone it down a bit, especially over the man's face. I am not a huge fan or the effects on his hand... they make it look really distorted and odd. The colors in this sig are nice. The last "L" in "PAYTOLL" is a bit hard to read because it is over a brighter spot of the background, it might look better if you shifted the text over about 5 pixels to the left so that it is over a darker portion of the background. Overall, it is a good sig, but the effects on the hand are not the best in my opinion.
