Looking to reapply, changes I should make?

I'm applying to MD and MD/MPH programs this cycle and am not having any success thus far, one Post-II waitlist and still waiting from my only other II. I'm looking to plan my reapplication now and am wondering what I did wrong/should look to improve on next time around? 3.56 cGPA 3.59 sGPA from a top canadian school, for what it's worth my school is known for grade deflation, but I don't think this is a huge factor to AdComs. 517 MCAT subscores:130, 130, 129, 128 US, Canadian, and Swiss... Looking to reapply, changes I should make?
