Inspired by spring in Michigan.
(It would seem the cold doesn't bother Anna either.)
EDIT: One of the disadvantages to drawing digitally is that I'll often find myself leaping to render my idea as it first pops in my head, to jump on that idea while it's fresh and new instead of thinking through and sketching other possible interpretations. For example, this was the original drawing, that once finished, I realized, it wasn't really working.
