The first one is really nice but the orange and blue building at the bottom is distracting, I would selectively desaturate that bit. I like the mood that you've created though.
Not really liking the 2nd one as much but looking at it technically, there are halos around the building (bright edges) and the clouds look a bit strange. Might wanna watch for that in future.
Agree with you about everything, actually. the first image was actually my second attempt, so the first image was more a trial run.
