Nice work.

if you don't mind me asking why are you making Nicephorian units? Are they for a mod that extends back into the 10th century?

In addition, since it seems that you are quite dedicated in this, many of the building models are western through and through (and also not very indicative or representative of the whole of the western middle ages but rather of the 15th century onwards ie in effect at the gates of the renaissance). It would have been a nice idea perhaps to make a fewnew buildings that are closer to Byzantine architecture of the time.
