Character Style Design

We had to create characters for a Filipino-themed comic we're working on for our Finals. My story was about a boy being the prophesized "Haliya", guardian of the moon, and with the awakening of the moon-eater Bakunawa, he must train to protect the last of the seven moons or the world will be in total darkness where demons could lurk in the night without the light.
We had to experiment with style while doing it.
