This image has a lot of promise Al and you have managed to reveal a fair bit of nebulous stuff between the main areas of nebulosity
It's a lovely image in general but a couple of things you might like to consider working on:
You have some clipping across the top, did you use flats? There is a bit of a gradient on the right, try massaging this away in PS. I can also see remnants of the blending work around the core too, it shows up as out of place dark hollows. How did you do the blending?
If you have a crack at these minor things it would be even better, still a nice piece of work
