Okay, I didn't do any more work on the picture from last night. Bad me! I'd originally planned to spend the afternoon clearing some space on my hard drive. I started with the digital photos. The first image I opened up was a sketch which i'd done on the till receipt from The Philosopher's Stone. So... erm, I scanned it and coloured in... as you do. It only took five hours.
I'm a bit crap at cleaning really.
