Is this what you’re looking for? Based on what you said above, I thought I would give it a whirl - good practice.
1. I imported your image into LrM
2. Sounds simple, but I tapped the “Auto” button. I often do this to see where Adobe might go with images. More importantly for me, though, is it’s the only way to get Auto White Points and Auto Black Points in LrM, which I find helpful starting points with full-toned images.
3. I reduced exposure by 0.3, reduced Whites by 10, added some Texture (+20) and some Clarity (+10). Then, I added a grad mask to darken the upper right ¼ (mostly sky) by 0.4 and increase the contrast by 15. Finally, I added a grad mask to the left ⅕ to slightly raise the tones there by 0.2. Note: there are two spots in the mid clouds (removed in this version).
4. Then I changed it B&W and Wow! What potential! I raised the Exposure by 10 and raised the Texture and Clarity by 20 each.
This took all of about 5 or 10 minutes. Very exciting image! I’d love to work with the raw file, if only to reduce the highlight in the top right that keeps drawing my eye. Great shot, MadDog!
Note: IQ on the images is not ideal as I could not upload the full res jpegs created, but had to reduce their size.
