They be lookin' a bit grumpy... I wish I could see where this freedom is. Is there an opening? From this POV, they almost seem to be running towards the fence. I like that the horses are well illuminated despite the dark surroundings.
stunning lighting and overall contrast and sharpness - distracting light at top could have been easily removed - goose the exposure of the far left green foliage and its a 10. 9. great job.
