This banner looks amazing on TFF dark, but when I view it on TFF light, it loses some of it's impact. I don't think it's a problem, since I believe that most TFFers have the site set to TFF dark anyway. I think that the splashes of the blue color give this banner some nice visual interest against the grey/black/white that is mostly going on in it.

The overall signature is nice and neat. It's very well organized and has links to some great stuff in regards to TFF.

I have no suggestions for improvement, because I like what you've done with it!
