Learning Abstract and Cubism

I always thought abstract drawing and paintings were just stupid random shapes thrown onto a paper, but I learned otherwise in class today. It's about how our brains work. When we look at things like guitars we usually focus on single parts of it. With cubism, each part is on a different plane and brings your attention to individual parts rather than the whole picture.

This drawing was a just a practice for what we are gonna do next week. We traced playing cards and added shadows and highlight to bring different planes forward and other back.
