Pratchett's Wizards - sketches

Was on the train to Dublin yesterday. It's a five hour round trip. On the way up, I was reading Pratchett's "Reaper Man" - realised again what a work of genius it is. On the way back, I felt the urge to do a few doodles based on the book. Here are a few of those there. They are very rough and unfinished, but a train isn't a very stable work area, and I was a bit tired at the time.
