I have been making sketches of these tree rings for years now. It is almost like an obsession. I love the repetitive yet different experience you get with each new layer. The concept of it depicting the life of something has always intrigued me. This image is a mess, but I enjoy the bottom half. The cropped version of this image is what I enjoy the most. There is something about the washes on the bottom right that really draws me in, maybe it is in its simplicity.
