The distance and center can be fixed with a tighter and better crop, and you will have to check what category you chose in order to fix that one. If the original is overexposed also, though, you may be SOL. That looks like a pretty bad overexposure, and doesn't look too good in terms of odds of improvement.
The white fuselage of the plane looks overexposed. If this was done in post processing (levels, curves, etc...), it can be fixed. But if the original shot is overexposed, there's almost nothing you can do to bring to A.net requirements.
Sorry to see that list of 'bads' - a bit disheartening. Hope you are not too downhearted.
The first thing that struck me looking at your photo was the top of the fuselage and the logos - looks more like heat haze to me than jaggies due to oversharpening. I was out with Tim and Jid last weekend and I was surprised how significantly the photos were affected by heat haze, especially as I was not really aware of it at the time. In those circumstances I think there is little that you can do in the post-processing. It's just a bit 'wobbly'
For me that quality issue is the key 'bad' - the crop leaves the subject slightly to the left and possibly a bit high, but those are more minor issues. Presumably the category issue related to the special livery?
I have only been uploading since last autumn - maybe the summer won't produce as many results in the sunshine as I at first thought. I have decided that my best photos were taken around Christmas time in the sun - nice low, crisp light and certainly no heat haze.
