Something seems to have gone wrong, and my last posts are not showing up. I hope this works.
 
This is my White Tower progress.  There are still a few textures I want to tweak, but for the most part I'm ready to call it done.  These images are all screenshots from Maya with no lighting.  I'm trying to decide if I want to try to render from Maya or if I'd rather take it into Unreal and render that way.  
 
The last image is the concept I was working from.  I took some liberties with color, and I know the building does not match the tower described in the books, but I liked the concept.  I found the concept on a Wheel of Time encyclopedia, and the artist is listed as Richard Boye.  (http://encyclopaedia-wot.org/geography/tar_valon/white_tower.html)
