The map looks already quite nicer, but isn't that great yet.
The "brickolddirty0076" texture has been overused on those walls. It really makes every wall look pretty unnatural, as the pattern is very recognizable (though it's a nice texture).
You've made those textures from scratch by the way?
What about adding height-mapped textures either? That would make you able to set the depth even better (as it sometimes isn't really paying off to use the normal-mapped texture only, which is for some textures the case here).
The lighting looks nice, but wasn't expecting less from that ;).
The map seems to be improved pretty much, but shouldn't be considered as done yet.
