I’ve noticed that I always draw dinosaurs in when I’m having major mood extremes. I was feeling pretty angry probably about nothing important (i.e. making no progressing in Firelands 25 mans) when I started this one. But it became a labor of love, I don’t think I’ve ever spent so much time doing so much exhaustive detail.
Personal favorite. Zombie Tyrannosaur. Approx: 13 hours, pencil.
