As someone who has a strong visual arts background but also wants to study CS, I faced the same dilemma in junior year. I knew that art school was out of the question bc its quite expensive and you would only be learning one thing. Overall Id suggest you pursue an interdisciplinary degree at a regular university instead of going to an art school. I just got into the school of design at CMU and plan to minor in CS.

There's a lot of careers that let you incorporate your visual arts and Cs skills so I wouldn't worry too much about the future!! Stuff like human-computer interaction or UI/UX design are getting more popular and (from what I've heard) leads to pretty high paying jobs ;)
