Illustration Inspiration

I find most of the art I like through social media, generally on my facebook feed from my artsy friends' posts and pages that I have liked. Today as I was scrolling though my feed I saw a woman named Irene Gallo posting a link to an article featuring tons of paintings of horses because it's apparently the year of the Horse now. 
Anyways, one of the paintings was an illustration by Ivan Bilibin for a book of russian fairy tales.

I'm attracted to these illustrations because of their flatness in comparison to other more realistic drawings. I'm also a big fan of the outlines of all the shapes and within each shape is one color, kind of like a Paint-By-Numbers.

And as for this last one, how could anyone not love a drawing with a woman using a skull as a torch and mushrooms popping up everywhere.
