Ok I took suggestions given to me by lockdowNn, knightKninja, and frag man and I made another sig. Tell me still how I can improve. I tried to make it to where the whole sig had something going on, and I gave my self a nickname because "eguitarplaya33" was kind of long.
Overcontrasted and monotone. Monotone gradient maps are never the way to go. The border isn't that great either. The composition is off, I'd recommend move the render up and to the left some. It lacks depth as well. You should look at tutorials and learn techniques and effects.
You went back to your old signatures... Work on picking the right renders. Make sure you position them right. Also, when you pick out a signature, you should be able to "see" what you can do with it. If you can't, make a signature and try out a bunch of random crap. Try smudging, blurring, etc. Also, you need more depth. Try to get objects to pass in front and behind the character. Never have just the BG and FG. Always have more to it. Otherwise you can just throw your signatures in as "free." Make your signatures worth something.
