Liberty, so many of my early entries were incredibly oof and blurry, so that forced me to learn to shoot so my pix weren't either. Maybe all you need is a tripod or a faster shutter speed.
I like the lighting and the framing of the main subjects, but there are a couple of things that I thought might have taken away from the overall picture. 1. The focus could have been sharper 2. the alignment of the front horses head directly below the other horse's posterior :) Good luck in the challenge!
