a nice photo with lots of things to delve into in regards to your interests, but I feel you have oversharpened this image and it detracts from the photo.
Obviously someone who likes horses, and the other details tell me this is the entry of a woman. I am going to guess this is from Snaffles. I might also guess Lynnesite, but she uses a Canon and I see a Nikon lens in the pic.
I like this, I think it feels like a nice, honest glimpse into a person (even if it was staged - good job). I like he lighting and the composition. Reminds me of those I-Spy books. At first I thought what I now think is a bit for a horse was handcuffs, hahaha.
