I have been admiring your night time photos as of late - you have captured some real beauties. Looking at the 3 in question I will say -
Number 3 - Lines look crisp and not too oversharp. Sky - however - a little blotchy (compression)
Number 2 - Sky - again a little compressed
Number 1 - Jagged lines on the plane and the sky is compressed
I have a crappy monitor - hope to upgrade soon - but this is what I see in the 3 photos you have in question. I am sure if I see this on my monitor, the screeners will surely see it on theirs.
Keep the nice photos happening Aaron - I think some of your earlier shots were so good that you have set a standard for yourself. I know this - the screeners know this - and maybe now - YOU know this !!
Good Luck !!
