A detailed, beautiful and dramatic fantasy photo of a huge old ornate bridge seen from far away, looking a bit like the "Basteibrcke" in Germany,on the edge of a huge waterfall inside a gigantic cave. At the central part of the bridge you can see a small keep. Torchlight is shining through some windows. The dark cave continues in the background.  Some moonnrays are falling through small openings in the cave ceiling. At night.
