I really like the concept and feel of the piece but I'm not sure of the render placement and light effects. I think I understand how you pictured the flow in your mind when creating the tag, but I don't believe that it's being executed at its best. Additionally, I think that your combination of green and orange is an absolutely fantastic idea, but I definitely feel they need to be blended further. On a last note, always keep in mind that text rarely adds to a piece, so its normally best to keep it out.
