Neat, you've really carried off the editing to get a "painted" look very well in the shot. And blended it nicely with the background and then added what appear to be scratches onto the artwork as well to age it.
Wow, I'm very impressed with the unique artistic aspects of this work. It's beautiful.
I've been around horses for over 30 years and this is one of the best I've seen.
Thanks for sharing.
