Entirely. My artworks have a very bright cartoon aesthetic (when coloured at least) but I my writer and I much, much prefer mature themes. You know, things like politics, philosophy, economics, heavy focus on character inter-relationships and such. I know most stories seem to have these, or at least try to, but they're never really handled in a mature manner. It's more like a teenager's perspective of how things work, which just isn't my jam.
However I've only made one comic to speak of thus far and contains no such themes. I'll be sure to come back and check out everyone's comics here when I have time!
