Absolutely spot on image Humayun
The colour you've picked up on the blue cluster located to the perifery of the Tarantula and to the bottom R/H corner is excellent as is the colour to the whole image.
As you say, this Nikkor lens you have shows its excellent quality proving it's flat field right out to the edges with pin point stars. Don't ever get rid of it, this is a keeper for life!!
Perfect combo taking in all of the LMC's FOV.
Top notch image.
Congrats
Cheers
