I was originally planning to do a Dire Wolf for D because I’m currently reading George RR Martin’s Game of Thrones and am really obsessed with it. But then I realized that Dire Wolves are not actually fictional animals. Apparently they once existed. Who knew? I could have stayed in the same territory and done a Dragon. But the idea of drawing a dragon made me really tired. So I went with Demon which is a fairly broad type of creature. You could probably draw just about anything and call it a demon. But I went with something in the “Mignola-verse” style because demons from the Hellboy comics are the only ones I tend to have any interest in.
