This really is beautiful, the soft and multi shaded background is anything but simple yet has not been over complicated and still allowed the eyes to focus on the intricacies of the foreground tree or, the less prominent but no less detailed branches in the back.
Yes. It was very light, since I did a more detailed, shaded thumbnail sketch in my sketchbook. I had an idea of the composition I wanted. So the sketch was just an outline of the tree in the foreground and the land.
