Metal Collage

I call this piece" metal collage" because I used various thin papers to collage on a black background, overlapping here and there.
I then sectioned it off using some of the collage lines, as well as adding my own to make a good design.
I then painted the areas, with various "metal" paints, steel, copper, brass, etc.
While they were still wet, I applied a Verde green patina to the copper, a rapid rust to the steel, etc.
I like surprises, so I just set it aside and let it do its thing. I was amazed, and pleased with the result.

I wonder what else I could do with this paint?? Any ideas??
