Sorry I'm not 100% sure which is the old and which is the new
... So, the one on the left has better stars but you have over done the decon/sharpening a tad so the nebulosity, particularly in the helmet, is all spiderweby and unnatural from the processing filter/s used. The nebulosity in the one on the right looks more natural but perhaps a little ringing is visible around some stars.....sooooo, if you can get the neb in the right image combined with the stars in the left image...NIRVANA!
The overall colouring looks spot on to me.
