I don't know what to say here other than to be nit picky as to why you didn't get a ribbon cause this is an outstanding entry.
Ok I had to think a little as to why its delicate...but I did understand that. So you meet the challenge.
The lighting is good, the composition is beautiful however that fence on the right side why didn't you crop it? I tried covering up the fence and yes I lost part of the tree but then the horse seemed framed by the trees and the earth.
As I said this is an outstanding entry and I had to get really picky to even question the fence but it is something you may want to play with.
Very pretty. The lines created between the bright clouds, horse and tree silhouettes make for a very pleasing composition. I'd like to see it just a touch sharper.
