I really liked the background. The text is pretty sharp too.
The cross just doesn't seem to belong as it is right now. It looks like a photograph that was 'shopped in an attempt to make it not look like a photograph. The result is a blurry object where everything else is nice and sharp. I'd personally rather see the cross get adjusted up to the level of the other elements or replaced with a new one.
That would probably look really cool if very lightly animated in flash. It already suggests that kind of motion, to me anyway.
I also thought that avoiding the bloody crimson red was a nice touch. That's almost more like a cool rust/sepia happening in that picture.
