The docked boat in the foreground with the silhouetted trees in the background works well here. The reflected sun adds interest, but the image seems too dark for the time of day. This would have been a great photo with sunset/sunrise colors in the sky.
This is really nice. The entire scene whispers AT REST. Very calming and perfect for this challenge. Actually, I think even one live "subject" at rest in this photo would have been distracting for me. Great photo.
