Sorry, but this one sucks. The effects look cheap and slapped on. I like the colors and idea though. Just try again. I think you haven't done anything in a while. It just takes some time to get back into it.
while i'm a huge fan of the tag in your sigspace right now, not so much this one; the colours are beautiful but the effects and the render just don't go along with each other. i definitely appreciate what you were going for though!
