What a wonderful picture! Looks like the new GR is no worse at preserving shadow detail than the old one. And no, I'm quite happy with my "old" GR II, thank you very much
Some basic edits in LR (mainly increasing contrast by pulling in the black and white points, as well as lifting the shadows and pulling down the highlights), then over to Color Efex and add half a dozen layers, back to LR for some local adjustments.
...and then put the resulting image through Silver Efex ("Fine Art" preset with a yellow filter at about 50%).
