Thanks for sharing. It sounds like you have a good feel for what you'd like to do and how the MBA will fit in and further benefit your skills and experiences, and that you'll aim to combine finance and law moving forward. All of that makes reasonable sense so that is a good start. You have exposure to banking and private equity to draw from, you have solid academics and some community involvement. Overall it sounds like you have a good start to your profile.
The GMAT as you know can make a big difference in what tier of schools you'll be most competitive at, and you have some of the top schools in the country on your list. Definitely be sure to prep thoroughly and maximize that score, and feel free to drop back by here when you have it for more feedback!
I would also suggest you brainstorm some about specific accomplishments; leadership experiences; impact you've made in your roles as that would strengthen your candidacy as well.
Good luck on the process and keep us posted!
