Wow...looks really nice... though in my opinion if the left side didn't become that dark so quickly...then it would look even nice i think... but thats just me...lol Great job otherwise!
I personally don't like the text either, it really does ruin the signature, also i think you should add a more solid background or a few more effects that don't just make it seem like everthings floating around. good job on it though i like everything really except for your text =\
I dunno i like the text it suits it. Its a very different peice quite unique, and im really feeling it. As was said maybe lessen the transition to darkness on the left a bit.
