Well I was bored so sat down and started drawing... Came up with this! It scanned horribly. It has a bunch more shading, especially through the shoulder, flank and face. I also fixed the hind leg, made the cannon straight from the hock to the fetlock instead of that weird bend, lol. I still can't draw ears, and the eye didn't show up under the forelock in the scanned version. I had a QH/Paint stallion in mind when I drew it, but I can't think of his name. He's a bay with a baldy face, and does either cutting or reining.
Here it is! Feel free to critique!
