Hi, Andy,
Well done! You've gone quite deep there in the outer, fainter, regions. Only because you mentioned it's not often done and it's one of my absolute favourites, here is
Trish's and my attempt from a couple years ago.
Yours covers a much larger area and shows faint extensions to the right that are out of field on our shot. You've also managed to bring out much more faint OIII than we did
I also see no scary skull and crossbones. Rather I see Snoopy the famous cartoon dog (the head, toward top left, is unmistakeable), riding on a salt-cellar rocket ship.
Methinks that the Hubble Palette is like a kind of Lingua Franca, and people who are used to it start to get an intuitive understanding about what the image is saying about the astrophysics, so I'd stick with it unless there is some really good reason not to.
Very best,
Mike
