my newest sig pretty random but i like it, very simple tho

If the middle had a bight light source this might look good.

This won't solve much, but I feel the need to warn you for future-reference:
When using Bevel and Emboss on text, move the "size" to "0". It looks much better.

hmmm its different and like dcn said i think that a bright center would look better.
