Hmm, is that just a 2d texture or what? Also, it would look nice if you had some bump maps on in, or uped the ones that you already put on the pillars.

Edit: Actually, in your first pic, it seemed like you had some VERY strong bumpmaps. Maybe fix it up a little, seemed very.........................."poky outy", but still smooth at the bumps. Sorry, really tired right now. ALso, I agree with the uniformity of the pillars. Maybe not model to differently (maybe just a little), but have most of the difference in the bump maps.
