A few things, @Stirlzzz
We know that religious artwork would be commonplace, and there is a heavy emphasis on symmetry so you may want to include that.
We can see some Kharbranthian architecture here:
Most buildings, even in Kholinar, would probably be relatively low down.
The Alethi warcamps seem to be semi-European in design.
Honestly though, we don't get an incredible amount of insight into the architecture so I'd use what you have, and not worry to much about it.
