Next idea for the tiny squared canvas

Today I spent a bit of the afternoon at Starbucks. I had someone drop me off. I wanted a moment to be solo. I had every intention of spending the time working on my Trina book but kept thinking of this canvas sitting by my desk in Easthampton. I've been also thinking of the idea of measuring time by the rings of a tree and so I began sketching instead. This is what I think I'd like to do next.
