Hopkins, Harvard, and Yale are high reaches. Your ACT is subpar for their averages, but I'm not familiar with your GPA scale to tell you if it's competitive. Your EC's are impersonal and not focused, but you at least have one leadership position.
As for your essays, different is good. Be careful about controversial though. It could be good or bad. I had a friend write about atheism for his common app and it was well-written. Despite being Hispanic and having a 36 on his ACT and tons of ECs focused on Comp Sci, he got deferred from MIT. I think his essay might have played a role in that, so don't alienate your adcom.
You are an URM, so that will play a part. I think you do have a shot at all these schools, despite some of them being reaches.
Chance back? Chance me for Wharton, Harvard, Columbia, etc.
