Overall - it's a lovely image. 

I feel it could benefit from:
- a little bit of darkening in the bottom left and right, and top right. It appears like maybe flat frame overcorrection occurred there or potentially overly exuberant gradient correction. 
- a global boost in contrast via a relatively gentle s curve. (Being wary of the stars, as you've got them about perfect)
- a global boost in either saturation or chromanence via the curves tool to bring those colours out just a bit more!

Again, its pretty stunning as it is, just to my eyes, the bright corners are a little distracting and there is an overall lifelessness due to it being a little washed out for colour and contrast.

It was indeed a very harsh gradient which I have struggled to correct, even after using multiple tools. I would agree I have seen images that have higher contrasts, and the corners are darkened, that look far better. Thanks for the feedback on the contrast and saturation - usually I have been overdoing it, and looks like this time I fell short of it!

I think it is overall a nice picture which could benefit by:

1. eliminating the brighter corners, they are not helping the overall impression
2. Increasing slightly the saturation
3. Making the picture a bit more crispy - maybe better said - get more power into the picture
4. IMO - the magenta tint of the background is not very beneficial - but that is probable a matter of taste…

Thanks for asking!

Lovely picture. I challenged that object recently and through this experience I can tell that you gave it a good end very subtle characteristic. The color Pallette is great as well. on my end, I gave it one more unsharpmask + self-ImageBlend to make it literally glow.

I will just say it is a great image. I recently… today, finished processing my image of Melotte 15. I think there is a lot of challenges in processing this area of sky. So much contrast in this nebula. I like your color palette. I only use OSC cameras currently, and without that separation of ha, sii and oiii from a mono camera it makes it even more challenging to get really sharp without the unsharp mask or MLT. Nice work!
