She's started a movement using Instagram (@justinablakeney) inviting people to join her and make foliage faces of their own. I love how inclusive that is - it's seldom that an artist invites others to "copy" what they're doing.
If you'd like to participate too (admit it. You do.), tag your pictures on Twitter and Instagram with #FaceTheFoliage.
Justina also sells some things that you might love on Etsy, like this Jungalow Mobile. I think she's a good artist for you to consider supporting.
