Well, if you're going to do a contrast thingy, maybe you should contrasr the color of the text to the right against the backround OR maybe it's that the left side needs a bit of a backround.
Ooh ma, I really like yours too mr.miyagi!!! Almost as much as Blaz3's. I think maybe the "X" could use some "flare", like adding some jagged edges to half of it? Although, it does fit together how you have it...
For now, I think I like aQwaBlaz3's best. It's just so dang awesome and simplistic. I think that white glow behind that nice X helps alot.
