very cool idea, I like it! Maybe just put a thin chain around the neck instead of the entire fabric? Right now it somewhat looks like you are cutting his head off.

Also, could you make two versions, one with just the cloak, and one with an attached hood from native which uses the same texture? In terms of the textures, heraldy would be very cool, otherwise just basic colors like grey, green, brown, black, red, etc. Maybe a generic white one so each mod could easily tweak that texture a bit if they wanted.
