It's probably worth being aware that making a living from your art generally is easier to do than making a living from your own original IP. Most creators I know make at least half of their income doing work for other people, be it working as a games artist, book illustrator, art teacher or even working in a related field like design, and I only know a couple of people whose own IP is their main income generator.
But the good news is, you can get your work in print and get fanart without needing to be a full time pro, or even a pro at all. There are lots of places you can get your work printed to sell at events or through an online shop, and if you keep updating and making friends in art communities, you'll probably get fanart sooner or later.
I actually started getting my first freelance gigs by making small press print comics. I used to team up with friends and we'd all make short comics, or repurpose ones we'd made to enter competitions and put them together in printed anthology books. Being able to split the cost across 4-5 people made it pretty affordable, and then we'd take them to events like MCM Expo to sell, which was always fun. I met a lot of industry people doing that and got some useful feedback to improve my work as well as making a lot of good contacts. Industry people are always impressed if you show them that you've made 100+ pages under your own steam!
Keep going, consider making short comics to shake up your style so you don't get in a rut, look for every tutorial, blog and book you can find on comics, storyboarding and art, and pay attention to what's in demand and what you can learn from popular comics similar to yours, or what you want to make, by reading them and taking mental notes, or trying to reverse-engineer their approach. The people I know who made it as pros are all absolute nerds about comics who will talk your ear off about the nitty-gritty details of technique, colour theory, marketing and stuff, so be a comics nerd and find other comics nerds to hang out and grow with.
