my question is, what focal length did you shoot these at? if I had to guess around 20mm?
the reason is that the straight lines of several of the buildings appear distorted (some leaning in/some leaning out), the most conflicting of which being the double shell roofed one near the middle. it just seems "off" to me
when making panos, I use the flattest lens I can and if I have to take 4 images to cover the entire scene rather than 2, that's what I do
also, often pano shooters will shoot vertical frames (6-8) and stich those together because most of your lens distortion and loss or resolution is at the edges. shooting vertically allows you to crop out a lot of that
Originally posted by Eder Too much blue for a night photo on 2nd and 3rd, first one looks more natural
there's actual a couple time frames during nautical twilight called the "blue hour" and the "purple hour". these occur within a couple hours of sunset depending on latitude and time of year. the blue in the 3rd image is very typical of the "blue hour"
with that said, it would might be the next photo session, if you can spare the time, give yourself a few hours and take images over the course of that time and note how the sky responds to your long exposures. you may prefer the "purple hour" or you may prefer full black and let the city light pollution tint things kinda yellow or green depending on the city. also you can get different responses with narrow apertures and long exposures versus a wide aperture and a shorter exposure, same lighting conditions, but they will have different effects on your image.
compositionally, I have no issues with the crops, but without actually seeing the 2 raw images you had to work with, I can't even comprehend alternatives (if any)
