Thumbnail # 2

Edgar Payne talks about the types of compositions as follows, Steelyard, the Balance Scale,  the Circle, the S or compound curve, The Pyramid, Grouped Masses, diagonal Line, The Tunnel, Silhouette, and The Pattern.
Here's an example of a Payne thumbnail (pg 120 Composition of Outdoor Painting) illustrating the Tunnel composition:

I attempted to use the tree masses from the left  and over the sidewalk meet the tree masses coming from the right. The sidewalk takes you into the picture.  The lighting was dramatic, being early morning illumination with strong contrasts. My marks and shape definition could be clearer so I'll need to work on that.
