Tricky one, really. One can just expose for highlights hoping the shadows will pop out somehow during doing computer magic afterwards.
Nevertheless, the reflection in the water looks great.
It's a great image Tim although it's hard to get a sense of scale. Are you using the DRC with the GR? It works very well on the GRD4 and brings-up the dark areas if you set the exposure for the bright light. It does not require multiple exposures, the camera simply does some in-camera processing by varying the sensitivity (ISO). I think it also works with RAW but is great with JPEGs and I leave it on all the time.
