Thanks a lot for the comments.
I was hoping to keep going with the life drawing exercises more frequently, at least three times every week. But I've been too busy trying to update my site and that has eaten at my free time.
Anyways, I was messing around with photoshop and made some "pencil" brushes and decided to put them to the test. Don't know how much time these took because I kept going back and forth with the brush settings. critiques and comments always appreciated
