Over all I like the image. However in my opinion image maps are not the way to
go to get realism. The problem with them is that you either have to make a
REALLY high resolution image maps or you have to repeat the image map and when
you do this your eye picks up on these repetitions, even if only subcontiously.
If you use a lot of them your image can start to look like a Quake/Doom/Duke3D
level. I would have used standard textures and just tweaked them a lot until
they looked super real. The extra processing time could have been because of the
image maps, though I'm not expert on this. Anyone else agree with me about the
image maps making the scene look like a Quake level? Another thing is if you are
looking for hyper realism as you said you were then you need to round out some
of these objects. You won't find many books which are mathematically perfect
rectangles.

Ps: I like the glass texture on column of the lamp post.
