c0nr4d, I suggest using a couple layers of clouds with different colours (make them black-white, then hit ctrl-u to get the colour you want) and in between them do a bit of brushing with grunge brushes, then erase some of the brushing with a differnet grunge brush. Now set the layers on top to different blending options (soft light, hard light) and you've got an easy backgroudn that looks pro. For example...

That's two cloud layers with two brush layers used ot make this sig.
