I like it a lot and agree with everything said. In addition, I am impressed by the stars - you have avoided the dark rings around them that is often seen in NB images when the star sizes differ between the colour channels. Apparently you managed to match the star sizes perfectly.

That really is a very fine image indeed, love the definition in the string of Bok globules along the lower edge.

One thing I wonder about these late-stage star-forming nebulae, does the oxygen concentrate in the middle because it's more massive than hydrogen and less easily expelled by stellar winds?

I think  it's because the [OIII] line, coming from doubly ionised oxygen needs higher energy UV than the singly ionised HII or [SII] lines.
