Very nice. I've never shot there, and I live 15 minutes from Saratoga.
As for the shots where the lighting is harsh, I tend to start worrying less about getting the head-on, walking down the aisle shots, and I start to worry more about where the light is good, and shooting from that location. Maybe this hurts me, maybe not. But I know that if the light is spotty/patchy enough that it won't even lend itself well to a B&W shot, then I shoot like that. It works well.
That's a beautiful guitar. Next time have the player take the clamp off of the head.
By the way, I think you have nothing to worry about. This is all beautiful stuff.
