Very nice result.
The histogram shows that the background darks are strongly clipped to black. That will lose a lot of faint stuff. If you can reprocess with the dark point set much further to the left, just left of the "foothill" of the histogram, you should bring out more very faint detail.
We wondered if the core of the galaxy might be a tiny tad on the blue side, but the
ESO shot also looks less obviously salmon pink than most galactic cores.
The star colours and the galactic detail look great.
