I don't know about this

If u use firefox than you will see that the BG is actualy transparent so it would fit to anything

I'm looking at it in both and it looks the same. Surprisingly enough.
I hardly ever use IE now anyway. But yeah, it does look a bit off center right now to me.

Yeah I agree with mannos, especially about that drop shadow. Make the gradients more subtle. And make that rope/wire/whatever sharper.
