Guys. I'm done. I did 30 covers in 30 days. Oh man it was harder than I thought. Not all of them are great, you know... but I do actually really like a few of them and I may turn them into full illustrations.
I also enjoyed doing these this month quite a lot. The support from the nanowrimo community was really great and I think next month for December, I'll do a winter/christmas/holiday theme for my sketches, and try to do one a day.
