Any constructive criticism greatly appreciated--I'm. new to galaxy photography and didn't realise just how different and complex it is.

I took the frames a couple of months ago but with a new 5 month old baby girl, time is at a premium!
Used Adam Block's M51 tutorials quite heavily including continuum subtraction for H alpha. I used Russ Croman's BXT,NXT and SXT extensively. Frankly, I tore my hair out trying to get the H alpha to work but I'm happy with the results apart from the star colours, which I did stretch and process separately. Not sure what went on there.
I'm not very used to imaging galaxies but my new 2550mm f/7.2 might change that. This was an LRGB image comprising of approx:
25x480s Lum
15x480 R,G,B each
25x900s Ha
Planewave 14" CDK
FLI proline 16803
chroma filters
Ultrastar pro OAG
ASA DDM85
