The sigs are pretty good for a beginner. You have a big potential.

A piece of free advice if you get it.
*Try to use some text which suits the signatures. You can find many of them by googling them. An example would be Daredevil font.
*Try position the render i.e. the player pic at a place where it looks nice. Randomly doing it won't do any good. Also be careful that you don't stretch the render.
*You are using lighting effects on the render which I feel is good for you. Try adjusting their opacities so that it looks nicer.
