That's pretty good Aaron!
In terms of some feedback, looking at the large version on Astrobin it seems focus is perhaps a little soft. Might be worth checking your subs using the SubframeSelector Batch processing script and checking the FWHM of each frame, perhaps discarding any which are obvious outliers. Looks like you've hit the noise reduction pretty hard too, it has a kind of mottled look in the dimmer parts - MultiscaleMedianTransform by any chance...? I'd be tempted to dial the settings on that back a little.
