Hi!
Thanks for your post. Ah.... an American in Paris.... love it!
Seriously though, do love Paris, visited something like 8-10 times when I lived in London and it's fabulous, hope you enjoy.
In terms of your b-school admissions ambitions.... first of all if I'm following, you would apply not this coming fall but the following, correct? Or did you mean this fall? Saw your planned work through 2018...
It sounds like your professional career has progressed well thus far. You have a decent academic performance and having the masters in accounting shows you can manage the academic rigor, though your grades in the masters are on the lower side. The involvement is decent, and the international experience could be a plus... I suggest playing that up and showcasing how you've learned to work well in various cultures, with all types of people etc.
To your main q of how you could improve... GMAT is solid; your school list sounds reasonable to me with a good mix of competitive levels.... the main things to do now include: keep doing your best at work; step up whenever possible and really show leadership where you can; continue or add a community activity at present; spend time researching schools; and dig in and do your career-related research.
