you honestly dont need to go to an art college to be an artist. and since it'll require all these prerequisite classes that'll reteach basics that you already know before you can get anything out of it, it'll probably be a waste of time and money for the first several years anyway. but your art is outstanding, i dont think you need a degree to back your skills. anyone can build an art portfolio (this thread honestly is basically portfolio level tbh) if they really wanted to get into more professional or commercial illustrating, but if you're sticking to it as a hobby, then you still can do some commissions on the side on top of your other job/source of income.
