I was at PAWCon and asked the artist about my badge. He said he was very slowly working through his backlog. According to what he said there are a lot more badges in the queue after mine.
Not wanting to make a scene in a crowded dealer's room I did not press the matter in person.
He was not taking badge commissions at the con, just some quick sketches. There was a note at his table that he'd be opening for commissions after finals.
