I think it looks great. Details in the neb are fantastic and the core is very well processed. Just putting my nitpicking hat on now as you've asked for suggestions and I assume you're looking at ways to get the most out of it: pic is a tad too blue, very slight field curvature on the top corners (P-FLAT IV works well for this). Also think that more neb can be extrated on the surroundings as you have very good quality data but that's personal taste. Maybe lower the black point a bit. Great shot anyway.
