There are lot of details, in a good and a bad way IMO. In a good way because there are lots of elements that make photo look "rich". In a bad way because there is no clear subject where the eye can "rest". My eyes keeps wandering between the horses foreground and the cows (?) background. But in the end the real subject seem to be the horses foreground. IMO the tree on the right (front) distracts the picture, I may have cropped that out (crop from the right and from the up). And also little from the left as there is half cow there
Photo seems to have nice tones. Although I may have lifted the shadows a bit, add some clarity (Lightroom 4) and add some vignetting (to bring out the subject more). Just my opinion. The photo looks a bit too neutral now for my liking (but I don't like overprocessed photos either).
Overall nice looking scene and well captured. There are multiple layers that make it interesting. River on the front, horses in the foreground, cows in the middle, hills and sky on the background. There is also a road that splits the image. The photo that is well worth saving and with a bit of tweaking, a worth of a print
