I appreciate art but it's definitely a bit of a saturated thing nowadays. Stuff like drawing animu & mango, as an example, it's almost a staple of the otaku culture, wanting to draw and publish their own mango.
You really have to stand out to pursue a career as an artist, especially freelance. The modern, effiency focused, capitalism driven world cares about results (as sushi >>447
mentioned); you must deliver them faster and better, cheaper than the others.
Unfortunately, to join say, an animation studio, going to college is a very risky endeavour, but not joining and you're underqualified. Maybe try looking for smaller companies to work in?
We all enjoy art, each with their favorite format (be it painting, literature, 3D, music, etc…). There will never be a lack of artists and I'm my honest and melancholic opinion, studying arts in college isn't all that worth it unless you already have a financial cushion. If you do already have a stable job you like, then go for it. If you enjoy it, that's what matters.
Ultimately, art is just another victim of consumerism, particularly in the digital and audiovisual medium. It's made to sell. Artists are PR machines at this point. "Classic stuff" like writing, painting and drawing, to a certain point, is becoming less valued, it would seem. But trust me: whenever I give a painting I made to someone, particularly portraits, the look on their faces is something else. You just feel it, the distinction between mass produced stuff and something with personal value.
The point I'm trying to make with the last paragraph is that you should continue doing it as a hobby. Something which you are intrinsically motivated to do. Don't regret not pursuing a career out of it. Eventually it would become something you'd do just for the sake of survival rather than enjoyment.
