The runway hear is implied more than seen, and is therefore not a strong visual element in this photo. Aside from this what I hope is a mild critique, I love this photo.
I tried to do something similar -- but I found that I couldn't get high enough to really see the runway. I 4-wheeled right up to the airport perimeter fence and set an 8-foot ladder on the top of my chevy blazer and snapped away until airport security came out to ask what the heck I was doing. Then I didn't even wind up using the shots.
I think that, as with my shots, a higher vantage point would work better to show the runway's "leading lines" -- but I like the color in your shot.
