Personally, I'd add a border. I like what you did, especially with the enlarged version of the awe-inspiring crowbar in the background. But please go easy on using the same render over and over again. 1 detailed and one repeated, should be plenty. You have a good background going. You should show it. Goes perfect with the color palette you have going.
The freed up space could be used to emphasize your name, because I could barely make it out of the background.

Thats funny...i have made several sigs for people...and when i see it uploaded..it looks blurry...so i would pm them and ask...they all say they did nothing.....i even made them another one...and it was still blurry.....i got into a argument once...because i made a jpeg and the one they were using said gif......they swear they did nothing to it....and i went over the sig(s) again and again........i cant explain it....and i still dont have any clue....i make the sig...clear and sharp (under the limits) and when they upload it...it becomes blurry and sometimes not even the same type of file......it has never happed to me personally....but thru requestee's....if you ever find the answer let me know
My best guess is the differene between uploading and hosting an image here, or hosting and using an image elsewhere.
When uploading an image here, one is required to place it on the server. Once uploaded, the image seems to have been converted into a .GIF image. .GIF's are lossless, but still compressed and limited to a spectrum of 256 colors. Then there's the factor of how the image is converted to .GIF, which might lead to quality loss, depending on how the original image is stored.
On the other hand, I've created and uploaded a new sig without any quality loss.
When you make comic book sigs, they turn out better if you go with the same artist, because artists or their artwork is their signature. Using two different signatures comes off uneven. If you have to go with different artists try to make sure that the styles are as close as possible. You need to have a real good eye when matching artists though. For example David Finch compliments Jim Lee's art style.
