O_o it's like floating asparagi in a purple soup, with a picture of a panther smacked into the corner.

lol
I have to be honest,

I'm usually positive about comments, but the signiture has potential if you can play about with the placement and blending of your render, give the background some depth/character, in relation to the theme. If you insist on using grass then I would suggest making it so that the stems didn't show. In fact here's an example m8...
You can go for the original grungy signiture, with some simple effects to make it more relevant:
[----------------------------- DEL --------------------------------]
However you can take the alternative, which is harder to an extent, because of the technique applique. That is to say vectorise your siggy

(practice and use some tuts first)
Oh and finally some essential things include, pixel fonts for quotes, clear definitive text, concise border (whether you use a chunky/single pixel, or more elaborate modelled one) and last but not least refrain your signiture size because smaller signitures have more impact on the eye. They also look better.
I will give you these signitures (i.e. make them with your name) at your request, but I first want you to give it a shot yourself

Practice makes perfect :P
