Looks fantastic! Both, the sketch from Caitlyn and your model.
But, look at the pic of Caitlyn, she actually draw hings, and your model shouldn't skip it as well!
Its a sort of "realism" that the viewer expects - even in a cartoony magical style environement.
The snow looks marvelous, too. Exeptional work!
