The beautiful paper creations by Canadian artist Calvin Nicholls (facebook), who imagines bas-relief sculptures of an incredible delicacy, superimposing hundreds of pieces, hand-cut with a scalpel. Each creation requires several weeks of work from the artist, and some need up to two years of work! Some detailed, thorough and impressive creations. In another style, I also recommend you the paper sculptures of Jeff Nishinaka.
