The wild horses will soon have foals, and that means the stallions will be battling over the mares. This was taken during one of my recent workshops with a participant's 80-200 (I had loaned her my 80-400). This guy is warning another stallion that he is too close to his band. Early morning light, D300, 80-200mm @ 200mm, f 5.6, 1/800, iso 400.
While the 80-200 is much lighter than the 80-400, I prefer the IQ of latter!
You captured a beautiful regal pose and the early morning lighting is really pretty. The horse may just be slightly too centered for my taste but it's not a big deal. I hope someday to have the opportunity to capture as beautiful an image.
With this picture, you really captured the essence of a wild stallion. Everything works here. I think this is your best shot of a lone stallion to date.
