Where to start...
#1) Night shots are extremely difficult to get lighting bright enough to show details in everything and still leave a balanced, appealing sky. The first two seem well positioned overall.
The engine on the first pic makes the fuselage look out of proportion. I think I understand what you were trying to acheive there, it's a fairly original perspective, but just a bit out of sync. To brighten the overall shot, I would try to get an aircraft with brighter interior lighting. Would have really grounded that section of the shot. I suggest also zooming in the ai and terminal a bit, just to fill the center a bit more and add a more interesting visual. Finally in #1, a bit too much black sky on the upper half of the pic. It kind of sets a dull, blocky overall feel to the pic.
#2) Great looking aircraft, but the appeal of the pic ends there. Not much to see after the aircraft...again just tons of black. Once again interior lights in the fuselage would have added here. Try to include more things to see and more of a storyline. Make the pics tell us something.
#3) Nice color, good sky lighting........imagine a row of tails one after the other, or each a bit behind the other...would create some ooomph to this one. Best of the three in my opinion, but I wouldn't click on it twice....think about techniques and visuals that WOULD make the viewer click your pic more than once....you know.. lights....camera....action....what are the chances of finding pics almost identical to these in composition and depth on SimV? Probably pretty high...you've got to create them in as an original fashion as possible. Think outside the box...go where no man has gone before....BE ORIGINAL!!
