From my Naruto/Atla crossover. Katara reincarnated as Iruka:
Rule of Balance, Will of Fire
Revised my previous design a little. And actually inked and colored it.
I really wanted him to have the hair loopies but the headband kept getting in the way. I was also playing around with the idea of a necklace, since it's so important to Katara's design. Then the obvious solution hit me and I moved the hitai-ate to his neck.
Aimed to make him look young, like about 16. Can't tell if I succeeded. I think the bigger and more stylized the eyes the younger the character is in anime. Maybe I should have made them even bigger? Or his face a bit rounder? Insights from more experienced anime artists appreciated.
