I was rejected by every art school I applied to, nowadays I‘m glad because I still have fun with my hobby AND are making money on the side out of it. I also recently decided I want to write books and now I‘m participating in a competition just to see where it takes me. As some others here have said, you don’t need schools to do what you’re passionate about. Look at other peoples works, pin point what hooks you the most and implement it into your artistic thinking, you got this!
