Beautiful Handcut Paper Art

I've recently stumbled upon this lovely shop in Etsy, which is filled with beautiful, seemingly simple, but very intricately hand-cut paper art, by a fellow named Joe Bagley.  He is a self-taught artist (an archeologist by trade), who has been creating and selling these fine pieces of art for several years.  I find his largest pieces of the leafless trees most fascinating - the kind of art that changes and gets more interesting the closer you move towards it, or the further away you get.  It makes me want to pick up my x-acto knife and start cutting...very carefully.
