On the lower level left side, you have a wye, which combined with your oval, can also act as a reverse loop. On the upper right side at the tunnel area, you have what LOOKS like a reverse loop wye, but in fact is not. If you can work in an extra pair of switches (just to the left of the tunnels on the parallel trackage should be one real easy spot), you can have an opposing reverse loop, which would allow you to change directions of a train at will. As it stands now, you would have to perform a backing maneuver at the reverse loop on the left side.
Otherwise, you have the makings of a pretty nice and interesting track plan.
