As others have said, you’re certainly a strong candidate for Williams. That said, I’m surprised that it’s your top choice given your interests in CS and graphic design. Have you taken a deep dive into the course catalog to make sure there are enough courses offered each semester that suit your interests? Also, CS is a popular major, and I’ve seen parents complain that their students are getting shut out of classes because they are overenrolled. While Williams may be more highly ranked on USNWR, I’m not sure it’s the best fit for your academic interests.
I would consider Colby, which has beefed up its offerings in CS and data science, and Amherst, which would give you access to classes at UMass, although I don’t know how easy it is to enroll in CS or marketing classes, at least they have a business school.
Good luck.
