Well here's the fully worked out version of my reject drawing. If it looks familiar, it's my take on the cover art for "Avatar the last Airbender, the Art of the series."
Mahalo is a mix between Avatar Aang and Song Goku from Dragonball Z. As such I depicted him with a battle axe to showcase that he has no squabbles about having to fight for real, which is very different from what Avatar Aang would be.
