Very nice. I wish we had a "thumbs up" smiley icon. My gut reaction to is is to feel that it's a wee bit too tightly framed.. as I always say, feel free to ignore this, my compositional or cropping skills aren't the greatest, but.. to me it feels a little claustrophobic. Still.. it's not too difficult to imagine that framed and sitting on a wall somewhere.
i really like this one, jim. i agree with dan that it is a bit tightly cropped. backing out would have given you the whole reflection in the water as well as some more sky above the mill for breathing room. that being said, i can imagine myself in that area so you did a great job capturing the feeling of the scene.
