I like the depth of the pictures - all the way back into those trees. Your one bright Cow in the forground marks a place for your eye to start looking until it wanders back to the cow in amoung the trees. I like the framing fringe of long grass at the bottom.
Nice clarity here, but a few things distract me. first, the bull way back there is too sharp and in focus. looks unnatural and takes away from the real subject. I would sharpen this so much, and I would crop that annoying bush out on the left side blocking the bull that is grazing. I hope there was a fence in between you and the cattle.
