After some talk with the commissioner, we determined they would prefer it to have a cloak rather than the scarf.
I based it on a mix of japanese snow bunnies and western snowmen. I wanted it to be partially made of coal since it's got that western touch to it, so I made it a little dirty around the edges, made jagged shapes for the buttons and nose, and gave it that extra ecological touch with the "spiked boot" pawpads to help it get around!
