I started out as an art major in undergrad, and I wound up switching majors. I think that med schools would like it, but the problem for me was that my art classes took up so much time. I found them much more time consuming than science lab classes, so I found it difficult to juggle. The classes weren't that mentally challenging, but the projects took up tons of time in addition to class time, which was usually 6 to 8 hours a week for 3 credit hours. It's definitely not impossible, but something you want to think about. There were other reasons I changed majors -- mainly that I realized when people were telling me what to draw and paint it took all of the enjoyment out of it for me. I thought that if I was not enjoying the classes, why major in it? I reasoned that I can always draw and paint on my own and switch to a science major, because at the time I was enjoying my science classes a lot more. But the draw back was, I became another boring biology major pre-med (albeit with 18 hours of studio art courses and 6 hours of art history/appreciation classes).
