hmm, i like it =)
The text actually fits quite nicely and the movie bar aswel i see a slight problem on the bottom bar though.. try lowering it =P
As for the render instead of softly erasing it try smudging it ever so slightly that way it will look like it's part of the sig an not just slapped on.. an if thats what you did try using the maple leaf brush set very small =P it works wonders. that's how i blend my render when i use one.
Goodluck on the rest of your sigs =) goodjob on this one.
