Put in another 2 hours, bringing up the total to 4.  It's not finished, but I think it's showing a lot of improvement over the last one.  I'm mainly happier with it because I think that he's starting to look a bit more "wild," whereas before it looked too similar to a domestic cat.  The ears and nose could really use some love and touching up, so I'll be focusing on that next.

Over and out!
