Have you tried a blind doodle yet? I call them Melissy Doodles because Melissa Langer started this on her blog awhile back. It's such a fun thing to do...especially if you're frustrated or having an art block. It frees you up and shows you the fun of drawing again. Give it a try and see what you come up with.
I did this one of Maisie in your honor today, Melissa. She gave me a "look" though...I don't think it was up to her artistic standards. HA!
