Chitin pauldrons without the ugly brown pads, closer to the earlier Morrowind game concepts. Named "Rearbrace" in the file, could go with "Light Pauldron" instead.
This is completed set of Telvanni cephalopod armor made by Siberian Crab. It can be used for Telvanni guards in some settlements or Telvanni's mercenaries. Armor made of cephalopod shells and leather and netch leather. I think it looks really cool.
This would probably be a heavy armour with very high durability but perhaps a not especially high armour rating (as it doesn't have a lot of coverage), favoured by chap-thil of the eastern clansteads. It's intentionally an incomplete set, harvested from juvenile siltlice whose shells can still be worked, if with great difficulty, but which are already too large to provide smaller plates suited for the limbs.
This is my proposal for an armour set between chitin and bonemold to be used by the lesser retainers of House Indoril, specifically Velothi in service of their lord, generally serving under Indoril lesser nobility: Orthographic concept:
