James,
I would say what is the subject? There is nothing to grab the eye. I just kind of wander around the frame aimlessly. It is a nice looking area, and good lighting, but there is nothing to grab my attention. I have a lot of these, I call them documentation snapshots. They are representative of being there, but that's it. You know there is a shot in there somewhere but just can see it. You feel the light is to good to waste, so you snap away. My HD is full of these.
This is where we need Roman and the Tokina. Perhaps something in the foreground would have helped, a lizard basting in the morning sun?
