Hi Julie,
thought I should give this site a try for a change and saw your nice sequence of images here. I appreciate the technical perfection of your pet photographs. The horse in the first picture is very handsome although the super-tidy stable in the background distracts a bit from the animal. Also, the reflection gives away thet you cloned out the reins - I'd probably have left the reins in the image or at least continued to use the clone stamp also on the reflection.
Please show us some more of the dog and horse action shots you are doing!
Cheers, Jens.
