Well initially I did not see the nail but now that it has been pointed out ---- It feels out of place.
the rest.... Spectacular. Maybe a teeny bit too much +EC but you may not have gotten the snow then.
Not much more to say that the other haven't already.
Gail you might have had the EC up a bit high, did you bring it down any in RAW? Still a very nice sq shot, good detail, I might have cropped him a bit more, then again maybe not. I'm trying very hard to find something to nits about:-)
