I'm not very good at celebrating my wins. I'm the type of person to withhold a reward until the work is done, then tell myself the work itself was the reward. But last year I sold my first novelette, a space horror adventure, and I decided to commission some art to celebrate its publication this year. I see artists advertise their commissions all the time, with reasonable rates, and it's fairly common for writers to commission artists for character sketches and book covers.
