I like the cohesiveness of your interests and activities. I found your post refreshing in that sense: it felt authentic to me.
Glad you are applying to Tufts- that came to mind for me immediately.
One suggestion: when writing the “why us” type essay, try saying it out loud or writing it as if you are conversing with someone in front of you. You can mention visits, location, size, class size and “vibe.” Many “why us” essays show research by citing specific professors and classes, which can be helpful but also can go too far. Subjective reasons are good too.
