Try a 16:9 crop, expand your midtones a bit more (darker on the dark side, about the same in the middle and nothing on the right). Then do a B&W adj later using these numbers with the blend set to luminosity. Something to play with.
I didn't touch the red slider at all. It's just a suggestion, Do with it as you wish.
Thanks for visiting but it was my choice. You know, I dont use too much LR and others tools like that, just my eyes to reproduce what I see at this moment.
