Good question to think about before you apply for art school or college. For careers in the art world, it would be good to have a general idea of what you want to study...industrial design is a great field, as are other art careers, but like anything else, you have to be committed to it. The art world is a very competitive one, and to succeed you need to be ready to work hard and love what you do.
Have you talked to your current art teachers about your future plans? They might have suggestions for you in terms of art careers and schools, and they might see strengths in your work that you don't. If your school has a career center, you could also talk to someone there for guidance about art careers.
If you are still undecided as to where in the art world you would like to work, but you want to continue your education after high school, then you could go to an art school, or even a college or university, and take some general art classes. College, art school, university is very expensive now a days, so when looking at a school take into consideration your family's finances and how much debt you are willing to take on after you graduate from wherever you get your degree. Be sure to check out financial aide and any scholarships offered by a school. Keep in mind, art careers don't pay very well at the beginning, so unless you are really committed to an art school or to a specific art career, you might look at your local state university.
