Passengers on the subway of life

The Halloween before last, I did a series of sketchbook paintings called "Creatures of the night." As with all of the paintings I do roughly in those journals, the intention is to create a full-sized, finished  piece. The question is which to rework and what medium to use for each. It's always a little hard to decide. I decided to do this one digitally since I've already got 2 paintings in progress. I used stipple and spatter brushes in photoshop.
