The top and bottom ones look like clouds with a plane trail through them. the middle one could be trees?
I see a texture or nap at the tops. I'm wondering what the little red lines are. They are well defined but must be tiny. Is this fabric, a close up of mustu? Fibers of paper, paper towel, a sweater? Concrete, old tile? Am I close? Nope! Are they dust bunnies?
the first one looks like hair!!!!
