Black negative Screen Prints

After using the Rayograms I liked the way it inverted the image and made the photo look like an X-ray. I wondered if I could replicate this with paint and hand made print. Here are the out comes of my prints.

I'm quite pleased with the prints as they work well as a train but I feel the first train of prints I did was better and less blurry than the second set of prints. I also unhappy as the white doesnt give as much detail on the prints as the test prints in black.
