Pretty Demon (s) (Patreon)

As a Sunday bonus (how appropriate it's a demon, isn't it? 😁) here's a demon I have started back in 2015.
I never finished it, because I did not really know where to go with the basic shapes, until I looked at it recently and decided the shapes and lines were pretty well placed and balanced already.
So I only needed to go into the details. That's what Sundays are for anyway, right? 😁
