I'm with Allan - much better and brighter on Flickr (I've had the same problem with some of my darker images - bizarre problem!)
I like the overall effect, but the camera appears out of place as, despite being old, it's placed in a scene with significantly older objects.
The unbalanced composition works nicely though with a nice triangle, and like I said the overall effect is nice (I like the sepia btw!) but it doesn't quite work for me because of the subject.
