I'll say the two biggest challenges in creating the world of Undershai is creating the Underspeek language (as seen on some of our signs) and trying to imagine good racial slurs.
I guess I really felt like introducing these three characters on one page instead of separate. Why? I don't know why, maybe it's because I believe in comics being freely made with as much random shit as there can be! Take the coloring for example, im no professional, things aren't incredibly the same on every page! My style encompasses different tricks and styles for every new page I design! Enjoy! ^_^
