Lovely pastoral scene, great post-processing (except for over sharpening).
Have you tried to flip the image? I think it would greatly improve the composition. This way two things lead to the sun first and foremost: being the brightest part, and the road itself. This kind of sidetracks the horse. Flipping would lead first to the horse and then continue exploring the rest.
It appears there was a split toning applied. It also seems it left some color cast in the sky?
