Nice shots

Really like the first and second ones.
A word of advice. I always try to keep the aircraft itself, unobstructed, in this case, by text. The 747 one is beautiful, but I think it would just top it off if you could see the tail aswell. Perhaps cutting it out and moving it down a little? You've got the advantage of having an all blue background, making that job a little easier.
Just my little bit of constructive criticism
