I think the lower part gives me a bit headache cos it's not blur enough, should have photoshoped to make more attention to the rings and pleasant feel for the lower part (below the rings).
Besides, to me, droping shadow of such thin and elegant font is very difficult to read (especially when the text is white, the background is light color and the shadow is so far away, difficult to read as a text with shadow, but rather 2 texts). If I were you, I would use outer glow with dark tone and smooth spread out instead of droping shadow.
