BA6 - Progress so far

So after spending a few days hammering down on producing the textures for my church I am somewhat pleased with the result, I'm not entirely happy with the result but I like it to say the least. The normal maps have turned out ok but they're a bit glitchy producing weird square patterns when zoomed in closely. This I hope to maybe fix with the help from some of the tutors. Other than that anyway below is a screenshot of a render using mental ray and a standard spotlight. All texture seen are from photos I took of the different churches from around Norwich. For most of the building I used 2048x2048 texture maps along with a normal map and specular map (where I felt it needed it).
