Thanks for your comments, Mike.
I think this one is just more special to me because of the subject and what it represents personally to me. This is my horse, Mouse, and I've said that I felt like it was she, who pulled me out of the ashes...or in my case, the doldrums of middle age-ha. I agree that this one is more digital compositon than photo and probably shouldn't have even posted it on a photography site but it does hold personal meaning for me.
Again, thanks so much for your comments and advice.
