"I think screeners do a great job, but I hope they keep in mind that not only photographers look at the pictures in the database, but also normal people, like me, who think this is a great shot."
Being one of the (formerly) "normal people" and a hopeful new photographer on here, I'd throw out there the possibility of resizing the picture to a smaller size, while increasing the pixels-per-inch ratio accordingly. Another thing that sticks out is how the horizontal stabilizer obstructs a good view of the tail logo. As far as blurry goes, the most blurred part appears around the wing root, especially the text on the engines, so maybe that's it right there... A.net is pretty high on aesthetics, especially since whenever there's a breaking news air incident on CNN, they seem to turn to either Associated Press, or (moreso) Airliners for the visuals.
From the shores of the sea we have come afar, we have risen high, among the stars.
