If I had one word of advice for fellow webcomic artists: do some zines. Doing zines has like, quintupled my income. It's ridiculous. I'm finally earning something resembling a living wage. I love long-form comics, but they are hard to monetize. Printing them is a pain in the ass. Short, catchy comics in PDF form have been so much faster and easier for me to produce, at consistently high quality, and they can be priced affordably for a wide audience.
