I like the shot, so many tails in one picture! However, I think too much Neatimage or noise reducing was applied. The airplanes on the left look like painting and the foreground is somewhat blurred as well. Also I think you have too much dead space in the sky. Sorry to be so negative as I like your shot but I don't think it stands a chance.
Quite interesting, with all those tails like that, but I think you are right about the quality. The tails themselves don't look 'right' at all, I would think this is a dead cert for rejection, possibly getting badmanipulation?
It's an interesting picture, but...
- Did you blurr/use NeatImage? Looks like the planes are made of plastic. This will probably lead to a badquality rejection.
- The size ratio is <3:2. Keep your shots between 3:2 and 4:3.
I'd try a re-edit if I were you and go easy on the blurring.
