I knew instantly that the poster related to the environment from the sight of grass. I think the grid method was a nice choice for this poster as well as the circular pattern.
Black & white - vertical stripes with punched out sphere revealing back of a woman. Basic, simple, but still I love this kind of art! Well done. Been messing with some similar art myself! This is blanc-pale.tumblr.com.
