These drawings are a lot lighter in real life, but I upped the contrast just to make it pop. I felt that other stuff I uploaded in the past just looked too light. I'm sure there are mistakes in these drawings, and I didn't draw any ground planes... just felt like putting these out and not fussing too much.
I think Jack Frost's staff isn't accurate. The only ref. I had on hand was the costumed person (Chris Bak) in front of me. This was a pretty good costume, actually.
