Not that these depict rain in any way, but since there is nothing much else to do while the rain is whipping off the windows, and thunder and lightning rolls and flashes overhead, I just thought I would play a bit. Luckily we still have power. And internet 😀
I think this looks like a little landscape of water and grassy hillocks.
This could be another little landscape, with a path up at the top leading out of the frame. Gosh I do love decalcomania art, every piece is a surprise.
