Thanks for the comments and criticism! I'll admit I probably went a bit crazy with the left side, but I wanted the right side to be bright, as I think it preserves the flow of the tag. I kinda wish I could've done more with the render though. Heh, dark Terminator = typecasting More C&C appreciated.
I really like how sparkly it is, and how it slides easily from bright to dark without there being a huge noticable change at one point in the sig.
Ok. Lot's of comments about the sparkle effects. Something to definitely think about. Thanks for the comments thus far!
