Downward angle on a huge spire

The Tianzi Mountains in China are incredibly dramatic as shown in this vantage point. There are dozens of spires like this everywhere, and with this particular angle you can see how huge they are. I estimated that this one is about 1000 feet high or equivalent to a 100 story building. I took this picture with a 24mm lens leaning out over the railing so I could shoot with a downward angle and avoid plants in the immediate foreground (I hate heights, but I did it to get the best shot). My settings were 1/60, f/8, and 640 ISO. The original sky was white so I added some ethereal clouds that made sense with the type of lighting I saw on the scene. I had actually photographed these clouds about an hour earlier in this same location. Usually, for landscape work, I use a smaller lens aperture.  However, with a 24mm focal length positioned relatively far from the foreground (I was about 50 feet to the top of the spire), I knew I'd have complete depth of field at f/8.
