Wow, fabulous capture of the moment this male deer calls out. Lighting aids is showing off all the great details in his fur to the texture of his horns. I'm on the fence on if it would be better to crop closer (say a square crop) to where it is just a head shot of the male deer. It would bring your audience closer to your main subject to see more details. The drawback is that it would be at a loss of that right antler that shows off the majestic beauty of this creature and some fabulous textural detail. Nonetheless, stunning shot and top notch work.
