Karen, I really enjoyed this image! I especially love the black horse shadowing the white horse. A lovely choice for this challenge! I wish I could take an image this powerful...:-)
This is very cool - the only thing that trows it off a little for me is the missing right hind foot - I now it's there, but where is it? LOL. Great shot, though.
The white horse really pops off the page - B&W treatment was an excellent choice for the composition. Love the sense of motion in the photo. The horse is presented as a powerful and graceful animal.
The tones are Great. The blur is pretty cool. If anything I would had like to see a wider view to give the horse more of a direction composition. The shadow of the horse on the left adds a ton. Nice
