Zuki and Heckfire - Hugs

While trying to do the numerous pics I owe (and stressing about several things IRL), I went on another sketch-bender like the one that spawned my muse, Skank...this time, however, it centered around Zuki.
Arguably the best image from it was this one, of her giving her "dear, grumpy Uncle Heckfire," which got me thinking about something I was told once by a psychologist: each of my major characters represents some part of me, and when I go on one of these "sketch benders," it's kinda like a food craving, I need more of whatever the character being drawn represents. It then occurred to me what Zuki, constantly smiling and innocent and prone to hugs and spontaneous outbursts of affection, represents: joy and love. Pure, unfiltered, untempered happiness and innocent delight at the world around her.
C'mon, Heck...would it kill you to smile once in a while, huh?
