Thanks for the criticism. I wasn't sure how to work with the black space, I tried some text, but I couldn't make much work with it. The focal, whenever I try to get it to stand out a bit more, it becomes glaringly bright, and I'm not sure how to bring it down.
The Color, I really was pained with. I had some light greens and blues in there, but it felt better with that. I'll post the greener version up with it, in a second.
Nice sig, by the way.
