Drawing humans is not as fun anyways x P
Have you ever tried figure drawing? Trying out quick pose studies without concern for detailing can be fun and really helps you practice anatomy from personal experience. And in the end you choose your fav[s] to finish. Or to get to know your sona, Hunter, better, drawings of him doing his favorite things or multiple expressions is always cool.Or lastly I wouldn't mind seeing Charlie again, he looked like a handsome design lol.

I don't know if that helps, sorry if not super creative ideas. Usually I draw what I feel emotionally at the time, what a song or music inspires that I am listening to, or emulate a style from an artist or drawing I admire [not copy exactly but more like take ideas or details and integrate them into our own style].

Thanks for the ideas, gonna try that :D
