I am currently loving the work of Casey Jex Smith and Josh Keyes. I know Casey personally and he's a great guy as well as a serious artist. Josh and I have exchanged a couple emails because I keep trying to get work from him, but it's selling as fast as he can make it. Anyway, they've both got shows up all the time so keep an eye out for them.
