Demon lord armament concept 1 (Patreon)

Ok I've started rought design demon lord ch3 character so any suggestion is welcome. I want Demon lord to have a weapon that's also living demon r that's can switch between normal weapon form into a demon. Basically ger armament is a living weapon type of demon that's forge from human souls. Currently I have 4 arm in mind. the first one is a blade. Still working their basic design and skin tone. Either they have same skin tone as their weapon form or they are all tan. Still have to go throught 3 more lol
