This works really well in HDR the tonal ranges you have caught through post processing really give a great visual sparkle. Because the colours are bright and luminescent the image becomes exciting. It could easily be called "visual candy". Nice cropping style as well and although I'm not partial to the border (it's me, not you ) I do feel it holds the image in too tightly for this car needs to fly and not be bound by the border. I do see tho' that with the border our eyes dare not venture out. A great shot.

I love standardbreds. Nice job composition the horses as a triangle at different depths with on the front in focus.
