The division between the pine trees and the agricultural land creates an interesting dynamic in this piece. It seems as though the road is going to take you somewhere mysterious and outside civilization and yet the sky adds a lightnesss to the darker presence of the woodland, making the overall emotion in this photo whimsical.
The sky really pops, but to be honest what I like best in this photograph is the elongated shadows extending across the foreground. It really adds something that I can't quite put my finger on. I quite like it.
