From what I see, you have nice viewing angles of trains approaching, traveling through and exiting your horseshoe curve. I especially like your view of the train on a curve exiting the main curve area. The elongated "s" adds a lot of interesting drama to train traffic.
That was something I was really trying to incorporate on this layout wherever I could. There are some areas where I was forced to have the tracks run parallel to the edge of the table but in places I had more space, I tried to create as interesting yet realistic trackage as I could.
