I didn't find out about this until yesterday, so I'm playing a bit of catch-up, but I thought it would be fun to participate. Here's my drawings for the first 2 days of the month, and I'll try to get up to date over the next couple days if I can fit it in.
For my part, I thought I'd try to stick to a singular theme for all my efforts, and since I've been wanting to draw more dragons lately, that seemed like a good one.
I'm sorta cheating a tiny bit with these - I'm drawing these in Illustrator rather than on paper with traditional ink, or even using a program like Sketchbook or Photoshop that mimics ink. I am using basically the same "inking" technique that I use on the Mythic Portal tokens.
