nice job, i hitnk that you need a more depth. and the 1 px borederisnt working. text is a bit bad too. for lighting try black soft brushes on soft light and and white brushes for the white light source.
Text is a bit hard to read and as nanSTA said, add a light source. Apart from that I really like the tag.
Pretty cool FX, but the flow and depth are a bit lackin. I am not diggin the colors on this one either, and the border and text should go. Overall, not too bad, just needs some tweakin. ^_^
