Composition wise, not good for all the pictures. Colours may be quite strong and nice, but overall, there is no focal point in any of the pictures.
#1 - slanted horizon
#2 - slanted horizon, and lack of foreground subject (typical of aircraft shots)
#3 - distracting lampposts and crane arms in the silohuette; may wish to move your position for better angle
#4 - no strong focal point; building and trees not forming a strong subject for the sunset shot
#5 - again, no point of interest. However, I do see some potential for #5 here. I propose a crop for more impactful composition as follows:
#6 - Distracting wires hanging from left to right, may wish to move the composition down a little using the rule of the thirds.
