Looks cool. Did you edit the meshes too?
I have been working on the imperial buildings for inclusion in 'mesh fix' in an attempt to get rid of the seams .

This is the one used for the Seyda Neen census and excise building , In the mesh fix variant seams have been eliminated by re doing the UV map in blender on the corner pieces and the horizontal seam on the walls that you see with some textures is eliminated because vanilla has 2 model parts for the wall sections whereas the mesh fix model uses only 1. The mesh fix model requires the wall textures to be adapted to look right in game but is simple to do and i will probably make compatibility textures for existing imperial texture replacers , and modders will be welcome to use the mesh fix models if they want to ensure users enjoy seamless versions of their work.

In the building used for Arille's tradehouse , there are a lot of seams on the lower wall section because seams tend to occur where model parts join and also because the two textures used don't always match. The walls in the vanilla model uses 2 textures and 13 pieces which don't fit together seamlessly , by contrast the wall on the mesh fix model is 1 piece and uses 1 texture and is seamless.
