Many people are just like you, don't know that is the bad timing.
some photographers still shoot around 8.00pm or later, as this is the time where lighting show starts, but they are doing multiple frames blending, and already took their base photo during the blue hours.
and some photographers do take photos after mid night, usually the theme is Insomnia or sleepless night in somewhere somewhere.
Shooting landscape/cityscape after the blue hours will give you black skies (if not light polluted skies). And usually dark (black) skies are boring, especially if the sky occupies a substantial amount of space in the frame. Unless there is something relatively interesting in the black sky, I'll generally avoid it.
Many people taking pictures at that time doesn't necessary mean that it will turn out nice. Their purpose of shooting may also be different. You may even realize that some are shooting landscapes with their flash ON and hoping that the flash can light the subject 100m away.
Also, as like DD mentioned, garbage in, garbage out.
For a start, I will encourage you to look at other's photographs of the same place.
Well if you are looking for inputs just for the editing alone,
Reduce the exposure.
I think you can add in some NR on the 1st pic for the sky.
Put a mask over the sky & add in strong NR, add saturation for some pop on the sky.
Add in some sharpening on the lower half with a mask, don't over do it or else it will be very noisy.
The shadow recovery might be a tad too much, made the foliage looks unnatural.
Add in some saturation after shadow recovery.
Adjust the vertical & horizontal.
Too much shadow recovery...Add some saturation
reduce the exposure
Reduce the highlight hot spot.
Adjust the vertical & horizontal....
