Thanks for the comments. I don't want to defend the photo -- you either like it or you don't. Just to explain the rationale behind it, I was trying for a composition which uses the wing as the starting-point that leads the eye to the rest of the aircraft. I wanted to emphasise the bulk of the aircraft and the size of the wings that are needed to bear its weight in the air. Far from getting all excited and snapping away blindly, I waited quite a long time to get the shot as free from obstructions as I could.
But in any case I'm sure this photo didn't get badmotive because the screener thought it wasn't pretty. There must have been a more specific reason and I'm hoping I can find out what it is.
Make the most of the available light ... a lesson of photography that applies to life
