The biggest improvement to your image (for me) was noise reduction and local contrast. Luminance around 30 was needed for my eye to be happy with NR. It didn’t appear noisy at all until looking at it 1:1. (i do prefer “some” grain in a lot of my edits).
As a side-note… adding back that -.66 exposure made it pop for my eye as well.
