I've recently been introduced to the work of Marshall Leggett, a painter working in Portland. I liked so many of the paintings from his site that there's lots of them included in this post- check them out after the jump :)
I love his layered illustrations over newspaper, scraps, and pages from books. It really makes his characters take on all new personalities when he incorporates this collage effect. Plus, his characters are super cute and he has an awesome color palette. His work is really affordable, and I would bet that it won't be for long, so you should take a look at what he has available!
You can purchase his work through either on his website, or in his etsy shop.
