sorry, toys just don't work for me. they can illustrate mastery of the technical aspect of panning, but without any more context, they really are boring photos.
Good Tracking. Use of miniature on simulated environment defeats a lot of the impact of motion. You do have some camera shake going on here too. Because the miniature is moving faster (relatively) due to size, your pan speed needs to be very fast and right on mark to pull this off. The top down angle, compared to a more side view really makes it apparent that this is mocked up.
