I did all these sketches on one sheet and didn't even use the whole sheet. First I did the tiny thumbnail composition check in the upper right, no details just large value masses. Then I enlarged the thumbnail a bit and added a little detail for the upper left sketch. Then I did a larger sketch, though still only about 2" X 3" with even more detail and some compositional adjustments. Will I attempt a painting of this? I don't really know, but it was a good exercise.
I wondered around a bit more and decided to do this little root study.
Obviously there was no intention to make a finished piece of art with this. Doing little sketches like this is important for two reasons: #1 it's just good drawing practice. #2 is that it's good observational practice. I'm always amazed at what I don't see until I really look, and the best way too really look at something is to do a sketch of it. There was a part of this little scene that I thought was a rock until I got to that part of the sketch and then realized that "rock" was actually another part of the root that had turned under and so was darker. I'm betting this sketch is looking like just a jumbled mess of lines to you, but for me it was invaluable observational practice, looking at this sketch recalls all kinds of visual details in my mind.
