The only real difference between these two institutions is that at a four-year college you'll have to deal with bratty 19-year-olds talking about Derrida, while at the art school you'll have to deal with bratty 19-year-olds talking about how they made their entire outfit out of doctoral theses as a comment on the commodification of culture.
Very few phrases (I'm thinking "self-published novel" and "this is a song I wrote about my recent break-up") strike as much fear in the heart of a right-thinking individual as "amateur artist". I'm not saying that's fair, because I trust that you're already thinking that. It's possible you are truly talented. Unfortunately, that doesn't mean you'll have any success in life. It's far more likely, though, that you are untalented, and while that doesn't mean you will necessarily fail professionally, it certainly doesn't work in your favour.
Why not instead spend the money you've saved on footwear or various kinds of sandwiches? Better still, why not give me the money you're willing to spend on art school? I don't have artistic ambitions, but I wouldn't mind going back to school to learn something practical. Then those temp agencies would be forced to take me seriously.
