Unfortunately I'd have to say the quality just isn't there. What kind of camera were you using?
Gate shots are a tough sell as they don't really show much interesting about the plane. Takes the right moment to get a good one. Also you tend to be shooting through quite thick glass (sometimes tinted) which has a tendancy to deter the quality of the photo. The half landing gear would also probably get it a motive rejection.
If you would like to improve it some I'd recommend some sharpening, cloning out the black spot at the top of the photo, as well as it looks like some CCW rotation but maybe it's just my eyes.
