These look really good!
However, as others have stated, there are too many textures as is.
HOWEVER, there are a ton of items that could be merged to deal with this. If we could get heraldic versions of some of the colored items, it could drastically reduce the number of items currently in game, while simultaneously increasing item diversity.
For example, there are: 4 colored shirts, 5 colored tunics over mail, and 7 surcoats over mail. If someone would make these, instead of having their own individual color, show the heraldic background of the player's banner, they could be reduced from 16 items down to 3. Additionally, I think this could be done for the two colored, non-heraldic transitionals, and possibly for the coat of plates, corrazinas, and brigandines. which would change another 12 items into 4.
This would take some volunteer work though, which tends to be exceedingly hard to find.
