That’s a lot of bumping. You seem to have lots of predictions, and I don’t really think there’s much that can be added to those.
Personally, I think a lot of people here are overestimating your chances in calling you a high match/low reach for Brown (high match/low reach means you have a decent chance of getting in). You’re an international applicant, so the standard you’re judged against is “are you one of the 200 best applicants in the entirety of the world outside the USA?” You have a solid portfolio, so I wouldn’t count you out, but don’t expect to get into any of the Ivy League schools you applied to (of course nobody, except perhaps Saudi royalty with a father thinking aloud of donating $500 million to the university, can expect to get in).
