it's hard to tell considering it looks like you lifted the shadows/exposure a ton.
I'll say.

How far was the exposure increased in post-processing? I can see the shutter was at 30s with 400 ISO so generally that should have be enough to get a reasonable night shot.
This is a temperature/tint-adjusted (to match the OP's shot), but otherwise un-processed shot in my collection that roughly matches the OP's sky exposure.

And this was a 20-second exposure at f/2, ISO4000.
For the OP to have gotten the luminance of the skies to where he did with a 30-second exposure at f/4.5, ISO400... requires a 5-stop push.
To get that strong of a purple haze and pattern banding (not the cyan stripes) in the shadows as observed, a 5-stop push is about right for a 5DS/SR.
