Mike Mussa, the guy at the bottom, is one of those cases where he's gained weight in recent years, but isn't quite a "fat guy". So it's not like drawing William Conrad, where you just start with a big circle, but his features don't have the distinction of his younger self. You have to shoot for somewhere in the middle, an unsatisfying outcome for a caricaturist.
But all in all, a very enjoyable gig, working with very appreciative people. Hope they call again!
