I think i've always been drawn to monoweight illustrations - especially if there is geometry, symmetry, and pattern involved.
Recently, I started doing some quick on-screen sketches to just see what I could develop. Often, the hardest things are the simplest things. These aren't 100% perfect, but I'm happy with how they look (both individually, and as a set.)
I wanted each composition/shape to evoke a certain feeling that is different than the other two. I can't specifically figure out which each one is (yet), but I think they are separate enough to be individual, but relatively similar to appear cohesive.
