Great shot. 85mm F1.8g is one of Nikon's sharpest but it does suffer from excessive chromatic aberration.
You could use the remove axial chromatic aberration slider there a tad as there are some purple halo'd stars from chromatic aberration showing. F2.2 this tends to weaken and wide open there is a bit too much.
Beautiful work. Would love to see higher res.
Possibly a bit more red/orange and saturation for an image showing such great detail would be my only suggestion.
