I'm intrigued to know how that title fits the picture! Nice shot, good use of the challenge to bring in a different viewpoint. Not enough shadow for me. 8.
For me, if the bottom portion of your photo (below the horeses heads) had also been dark, your photo would have a greater high contrast impact. The straight white line above the dark horse is a little distracting to the eye, but what wonderful clarity and crispness.
I loved this the moment I saw it. I like all the varying levels of their muzzles. They all have an identical expression. The contrast of the dark one against the light is great. 8
