The background is a bit streaky; I didn't crop it to avoid losing the barely visible outer ring.

In the original size, the high-frequency noise on the nebula itself is very noticeable. If you clean it up, the detail won't be degraded, and the impression of the image will be better.
Also, in my opinion, the saturation is overdone.
