Possibly my last Christmas-related art for the year. For those who don't know, Grýla is an Icelandic giantess troll-like witch who eats bad children around Christmas. A bit like Krampus.
In most folklore, she has hooves for feet, but there have been some adaptations that have given her feet that are otherwise. I actually didn't know about the hoof-feet before drawing this, so just take this with a grain of salt, I suppose.
