Extrasensory Perception

This is my silverpoint drawing from my "Everything Book." It started out as just a doodle to experiment with the medium, but it kept growing and grew into a composition I'm pretty happy with. I think I would like to take this idea and develop it further in a painting. I can't say I really like the silver point as a drawing medium. I need to be able to erase, and it is not dark enough to create a wide range of value.
