It took me a while to figure out what the proper interpretation of the goblin stick figure feet would be in the upgraded style. In last year's calendar, I had him barefoot with the old-style three-toe foot, just in green. And it looked weak and unthreatening, and I didn't like it. When I started working on the O-Chul story, I came up with new goblin footwear for the enemy soldiers in that story, and I liked it enough to bring it over to Redcloak.
So starting now, armored goblin-types get nice heavy boots instead.
