As I mentioned before I decided to keep the transparent plastic as a mask - instead of a paper one originally intended - as static electricity kept it in place.
When I spray painted I then got this unexpected effect - the plastic curled and created like a frame!
I liked this a lot; it became more iconic, but at the same time kind of trashy
fake, plastic, baroque
I had to take the plastic away though. (In this room and with that light it was still ok, but not as good as with the plastic on)
