One word to describe this.....................
SEXY
only problem some ppl will bring up (depression *cough* lol) is that it look monochromed but i think its a sexy monochrome
Yes, the colors could use a bit more variety. But the real problems here are the text (get rid of it) and the blending of the focal. Despite the color scheme already blending the focal in most of the way, you need just a little more to make it part of the tag. May I suggest some foreground effects?
