You know, when I saw the title, I immediately thought of the red-brick work fort that is symbolic to the Mughal rule in India. But to my dismay, your picture did no justice whatsoever to the Agra... To put it bluntly, it seems much more like just any other passageway IMO.
I think I understand why you like the picture: a number of elements in your picture are quite symbolic, from the jail-like grill opening from a basement like dungeon, person (?) running away from the frame into the light. If that's really your intention, why choose a neutral title such as "passageway" (and mention about Agra)?
I like the picture mostly because of the links... but in terms of execution, it's far from anything spectacular. Just to nitpick on some technicalities:
(1) the whole frame is not straight... which enhances the sloppiness, and reduces your intention;
(2) the use of sepia make the picture look old, which is probably contrary to your intentions. Why should a thematic transcend from darkness to light be old? What's so nostalgic about that? I think the picture would work better in just b&w instead.
(3) while you use the overexposure to indicate your theme, you should try and do some digital imaging as well, to add in some light rays, instead of just an overblown entrance with no definition. Similarly, you should also burn the doorways near the blown-out entrance as well, to give the light more impact.
Nontheless, I like your idea. Got potential to develop this much further into a series.
