I've decided to let go of my "particle river" idea (see below) and go back to the simplicity of my original sketch. I do want to add a little more depth and texture, though, so I'm going to try something new. The photo above is a closeup of an experiment I did on this last batch of prints. I scratched in a few lines with a leather punch to see if it would print intaglio. Intaglio is the opposite of relief printmaking. Instead of raised uncarved areas being the printing surface, what prints in intaglio are incised areas. In the intaglio process the damp paper is pushed into the incised grooves, which hold more ink. Usually, intaglio is done on metal plates in processes like etching and aquatint. But my experiment reveals that a subtle sort of intaglio can be done on wood, so I'm going to try it on this print.
