Hi Joe, a very
'regal' pose and the contrast between subject and BKG does make the subject pop to a degree.
Overall it lacks that
'black' it appears quite light, not even in the darkest shadows does it get to 100%, using the Tone Curve, but better PS Curves, as you can pull more out to make the subject more striking, more Darth Vader.
A bit more of the post would be good, its a bit tight to the trim. Talking of that do you check the box in Lr
Enable Profile Correction as the post verticals look slightly out, so may be if the LH line of the post is vertical it may help??? Small I know but its subtle differences.
TFS
