You know at first glance, I would have said this photograph is too dark in general. Then I did a quick double take.
What I noticed was that you actually (intentionall or not) added a natural gradient into the photo from white to black, with an orange emphasis, from the top left to the bottom right.
I also must note that the use of the gradient adds a detail to the quality of the picture which puts it above others.
Great job, I really cant say anything bad about this one at the moment. Later, I might return here and edit this to see if I can make any improvements and let you know!
