Jon - Those are some cool sheep and you have captured them well, but I stand by my blown out sky comment - it really makes it hard for me to focus on their faces as much as i would like.
So I just came from your black and white bug photo to this shot of sheep with black and white faces. lol what a transition. Did you take this from a car window? I don't know why but that is what the blur reminds me of. Get a zoom lens for your camera and get a close up of one of the faces - I bet that would be pretty interesting.
Those are some cool sheep faces - I have never seen ones that look like that before. I like how they are watching to see what you are going to do. I think the bright sky is a bit of a problem for me - it seems to swallow up the sheep.
the crop here is too tight I think, it gives no sense of space or scale. The focus is way way off and the central horizon line i think is a bit thoughtless. Overall, it could have been great but there's a few factors that hinder it severely.
For me, if that pole in the back right hand side were cropped out, I would like it better. My eyes keep getting diverted there and they don't look too long at the sheep themselves.
