I'll be the contrarian and say I prefer the original. Love the way you got those Ha areas. It doesn't look oversharpened to me.
You often have a sprinkling of green stars. Keep in mind airglow in an otherwise totally dark sky can give green light pollution. Some nights it can be quite intense. See this nightscape:

That green is not accentuated and was real. That was the greenest night I have seen. I did not know the sky was often green until I started doing nightscapes. Now I see it more often than I don't.
It often confused me how come I was getting excess green in some images despite imaging in a near zero light pollution site. Airglow was the answer.
HALVG is a free plugin for Photoshop and is a Photoshop version of SCNR noise reduction tool in PixInsight. It gets rid of the excess green and makes it way easier to balance the colour.
