4 Character Concept Variations

Here are 4 different ideas/variations for my character concept. The following step will be finding the final version of The Wanderer (my character) in order to create the model sheet and then the final rendering.
The ideas and key words so far are:

Character with supernatural powers. Resource of power : Gem
Gem is found in a temple.
12 steps of the Hero's Journey/Awakening/Rediscovering the self


split in half sword:

magical cloak/camouflage/shape changing cloak through particle effect/shadow/smoke

gem(source of power). The gem lays on the sword which allows the sword to split in half.
