Artists who create artwork using only paper run in to one major problem with the medium- the flatness.
Without ink or paint to create the illusion of depth, shading and shadows those cut up pieces of paper end up looking way too flat, and flatness in artwork is far from impressive.
The geeky and colorful scenes created by Brazilian artist Nathanna Érica are anything but flat, and although she does use a little ink or paint here and there for texture her pieces are pretty much all paper and absolutely awesome!
Nathanna sells prints of her artwork and the pieces themselves through her Etsy shop, but if you want to look at it all over and over again 32 of her works have been collected in the art book Samba.
