yeah, a different theme from the current one will be good.
In this headbanner, and I think toward the bottum of it is too white, the angels(?) get sort of blended in, which makes the focus of the picture rather weak, maybe make serveral clouds instead on one big one at the bottum, this will make the angels stand out more. In fact, it looks more like fog instead of cloud, just like you started off very well at the top, but at the end you rushed it and just smudge everything, which gave it a bad finish. Dont know if you understand all these...
And this maybe off-topic, but
I think scott needs a cooler name, Scott does not sound like what an administrator would be called, get a more unique or special name.
