Looks pretty cool Doug.
I think you got the balance right. Star colors are nice. Ha blends are not an easy thing to do. I usually get rid of the blue hot pixels from the QHY8 with the healing brush in PS. Also if you check those faint little lines on the bottom half of the picture (white dotted trails) I get the exact same thing very often with the QHY8. I think they're caused by hot pixels (but in the Ha Lum) as well and they're offsets by the same amount because the subs are offset when the guiding is paused or momentarily stopped between exposures during the imaging run. I get rid of them in CCD Stack with a rejection algorithm. The ones that still make it through I'm back to the PS Healing brush
