Verdigris backgrounds

OK, I admit it. I enjoy playing with the Gimp and trying out colour schemes. And since it turns out I misunderstood what Amoeba was getting at a few posts back I thought I'd try again. It probably doesn't help that I'm unfamiliar with Exalted Infernal.

Anyway, this is the one I cobbled together for the last lot of images.

This is the new one. I started out with the streakiness in this one,  overlayed some colour on top, and then attacked it with a few grunge brushes. It looks a lot more like a real surface than the first one, so that's got to be good.

On the other hand, it's still a bit green. So I took some more grunge and slapped some low opacity red and orange on top.

Not sure which I like best, really.

This is green dominant on background #2

Same with yellow dominant

And with the third background:

I've been looking at these so long now, I just can't tell any more...

[edit]

OK, one more:

Threw some more red and black at #3. I quite like the result. I'll have to try sticking the controls on top of it and seeing what that looks like, But not right now...
