Hello,
Overall your profile looks strong for your
target schools, which encompass both reasonable reaches (e.g. Wharton) and on-pars (e.g. Ross). Given your overall profile including goals, some other schools you might want to look at are NYU and MIT (reasonable reaches), and Darden and UCLA (closer to on-par).
There is no need for
your application to be bland, if you execute it effectively. What will make it engaging, distinctive, and memorable are the details of your experiences and the unique insights/perspectives you draw from them. That involves skillfully using anecdote, example, and detail. Don’t look for some big, dramatic, or exotic thing to differentiate yourself. Rather, delve deep into the specifics of your experiences, which inherently are unique and yours alone.
Your GMAT score suffices -- it's OK and does the job. Of course, higher only helps. It would make sense to retake IF you are pretty certain you can score higher with a reasonable amount of effort.
