Looks great! But there is one small compositional flaw that I thikn when improved will make it even better. As you can see, the rider is riding to the left. As it is now, he is close the the left side of the picture, so the viewer is pushed out of the frame of the composition because they are being chased by the rider. You always want to lead the eyes into the composition. (Most of this is from reading a really good online landscape composition tutorial here: http://www.wetcanvas.com/Articles2/135/120/ ) I suggest either turning the horse and rider around, or if you like them this direction, move them to the right third of the frame. Then you might want to swing the camera up, left, and overhead a bit to reveal more of the rider (as he will be smaller and more obscured by the rock when h is moved back to the right side) My 2C.
