Here is a close up of the basic drawing for this picture. The picture could easily be just this part but extending the format and showing more fields, trees and barn in a subordinate role makes for a more isolated, cold feeling. (Ah, sweet melancholy!)
The washes were done by a light layering of watercolor pencils and wetted and smoothed out. For the sky I prefer to put the paper upside down. The sky was more blotchy than I liked so later it was rewetted and smoothed out with a natural sponge.
The trees in the fence line were traced on and preliminary coloring done lightly with indigo colored pencil.
