Chris,
I don't usually like suggestions on other's photographs, but I did something accidently just now that got me thinking about your shot.
I was scrolling upwards, and the screen cut the image just inside the dark area below the light patch on which sits the foot of the ladder. For me, it instantly made a tighter, much more focussed and less complicated picture. If the EXIT was made more legible it would create an even stronger sense of the guy cl¡mbing out of this world and up into the unknown.
