Love the horses, they are beautiful and your colour and exposure are great. I can't help but wonder what they would look like in a field without the distracting fence though.
A pleasing shot, but in the context of this competition needs something extra special to break out of the 5-6 zone. One thing - you need to lose the blue rope, it drags the eye over to the left.
Excellent tones & levels on this shot. Detail is very good without being over-sharpened.
The subdued background works well to add dimension. Well done!
