Bark of the Ponderosa Pine, watercolor

This painting was supposed to be part of my "zoom in" themed pieces, (along with River Rocks and Eye) but it will not be included in the Rancho Cordova City Hall display because it took me too long to get this finished. In fact, I'm still not sure it's finished.
The idea originally came from some reference photos of a ponderosa pine tree, with its bark that looks kind of like a jigsaw puzzle. I started by tracing a few shapes with pencil, but then let my imagination run wild with the rest of it. The bark seemed so simple at first but then it just took on this whole other feel, very abstract. I am not one to do abstract painting so my brain keeps telling me it needs something else, so I kept coming back and adding more layers. I have finally said I need to step away from it and call it done.
