Holy Cow this is only your 2nd LRGB image? Amazingly good.

Round stars, lots of detail, you got the vertical dust plumes, colour looks good perhaps a bit too much blue in the background. At AAIC in July Martin recommended a higher percentage of RGB than 1 hour out of 8. More like 25-30%. When you consider a lot of the noise in an image seems to come from the RGBs that makes a lot of sense. I have started doing more RGB as a proportion. I think it helps with the processing with less breakdown and more able to control colour noise.
