Just a few random thoughts.
Don’t bother reporting the 35 ACT. With a 1590 SAT, why run the risk that you look like a “test drone” by submitting a different test result that is actually lower?
Are you at least 25% Hispanic? Did you take the PSAT and will you qualify for National Hispanic Recognition Program (NHRP)? No need to hit the schools over the head with your ethnicity, but do not discount it if you are at least 25% Hispanic. It is a hook at Harvard (and likely Georgetown), albeit a relatively minor one.
Last, I would emphasize your interest in physics and any accomplishments in math/science. This is helpful for a female candidate. Physics and IR is an interesting an unexpected combination, I am sure there is a great essay lurking somewhere within the intersection of those two ostensibly different fields.
Best of luck, and congrats on a terrific high school record so far.
