um.
how do I say this nicely...
that entire structure should fit on one 1024. All your pillars should share the same texture (just rotate them differently if you want.)
You wasted so much texture space I literally gagged on what I was drinking.
If I were you I'd start over again and FORCE myself to do it correctly.
As for having a normal map. That seems a bit suspect. Your diffusion layer (the color layer for you kids at home) has a bunch of shadow detail on it. You beveled and chipped things out. You should kill all the shadows and highlights and let the normal map do its job.
Makes a pretty render though.
