Actually John Paul Strain does a fantastic job as well. One of the best pictures I've seen is of Stonewall Jackson first meeting Sorrel--they're cuddling and making kissy-face, and it's just adorable. The only trouble is, he chose a bay to model for Sorrel; how crazy is that? One thing I like about Strain is that the horses' coats match the season appropriately. Graham depicts horses in midwinter with shiny coats instead of furred up like a yak. That chestnut is so shiny he looks like he's about to be entered in a strip class at Devon.
You're right. That's clearly a bay, not even a bright bay.
What's with that right fore hoof, though?
This one's good:
My horse will jump like that off irregular ground, without planting the feet square.
Forrest was a genius, though as my grandmother would say, "Someone you could not possibly invite to dinner."
