Interestingly, the thumbnail does no justice to the full range of tonality in this photograph. As is, it's a good representation of what was there. You might consider making it a good deal more dramatic by printing that sky with much greater contrast and more ominous darkness. You've printed the score, now wring out the performance!
It's tempting to increase contrast but its deceiving gentleness is full of drama as it is. If I had the camera I'd be working out how long before the storm reached me and if I'd left the car some way back whether I could reach it in time.
Or if I was with my wife and with illusional safety in numbers, I can imagine me saying to her: " This is slightly surreal looking" while staring at the scene and her, being much more practical, tugging my arm and saying:" It's time we left"
The fort is a difficult place to photograph well- at least for me. You've really nailed it. ditto JOVO's comments on adding just a little more drama... remember, you CAN feel all the ghosts flitting about there, even in daylight.

I really like the silvery feel to this print...I'd be kinda worried that higher contrast or a heavier printing of this image would take that feel away.
