Adventures through time characters

Concept art for a potential webtoon that is constantly switching between a Futuristic past and a medieval future exploring the fictional world of Usan.
This is a project i had worked on for my senior thesis class in my minor (Concept Design for Animation and games).
We were tasked with creating a story that involved time travel.
I would love to eventually turn this into a an actual graphic novel someday but since world building isn't my strongsuit (yet!) I'm going to put this project on hold!!
