Are you talking skins in a similar vein to unit textures already found in-game, or something else? I’d send screenshots if I had them on-hand, but the best I can do at the moment is point you to my personal overhaul mod, specifically the Myrmidon (I think heavy & champion), and Medjay (all tiers) units, where you could view them in the editor.

Though others here are definitely more experienced than me….

Yes, oh interesting mod, i'll give a try. But my services are for adding unit to the game , texturing and such.
Its mainly to add romans, carthaginians and celtic units to the game but for the moment only for editor battles

oh, nah, I didn’t mean my mod was what you might be looking for, sorry that wasn’t clear; I just meant like, “here are examples of units I have retextured, as a measure of my ability.”

at any rate, what you are looking for sounds like it’s currently beyond my skill - I might be able to hack a few of those types of units together, but until I try my hand at, and get comfortable with, proper modeling, rather than just texturing/skinning, I don’t think I could deliver to your satisfaction.
