Bill is still sculpting and painting figures. I have a feature on my blog which shows 360º Hi-Res pictures of his work. Usually I'll upload one figure a week, but sometimes I change it up a bit with other great artists.
You should try to make it to the Chicago show (in Schaumburg) in Oct. since you're in the neighborhood. Bill is usually there and will likely have a few of his latest figs - not to mention all the other excellent artists that will be there.
