One aspect of Rockwell's art that fascinates me is that it's almost always about people, and I don't recall a single person in a Kinkade painting.
(Okay, except Looter Guy.)
The horse (especially the horse, but also the guy at the front door, now that I look at him) is way out of drawing. The legs are attached to the horse incorrectly and the neck is wrong, and horse's heads don't look like that. (He also doesn't know how to draw a horse collar, or a sleigh harness, but that's a technical matter imperfectly researched.)
