I'm not only a webcomic writer, mind you.

I've been giving standard comics a go as well for several years without ever coming close to broadcasting them to a wide audience. They were mainly about two superheroes saving the French city of Grenoble from a variety of silly villains, but ending up critically wounded at the end of each episode.
The character you see on the right is the ever-so-smiley receptionist of the hospital they kept being rushed into.

Due to my decent drawing skills and to my imagination, and to the fact that I'm very prone to picturing silly ideas, I draw a lot.
And I mean an awful lot.
What you have there on the right (click to enlarge) is an attempt at a female version of Team Fortress 2 while retaining the male characters' main attributes. The positions are the same as on the second version of the original group picture.
And then a few pictures of the individual classes.
