This is yet another sketch I completed a while ago which I then decided to digitize.  This was a failry large file for me, containing many layers, gradients, transitions, blur effects, patterns, etc... I probably learned more about illustrator with this piece than any other piece previously.  I also messed around with photoshop on the original scan to create something that might look like a carving in a cave.  This was a refresher for me as I spend more time drawing a bit more abstract pieces.
