Some Sigs

dont have time, but your definetly an ammature.

work on blending, depth, backgrounds, and text

 

Im guessing your kinda new to signatures?

Look up some smudging/sig tutorials and get familiar with the program your using. (is it GIMP?) They would look better with matching color BG and some smudging. But work on those and you will be golden in no time.

And also work on depth

 

My pic is the best....
not.
