HBS 2+2 is a great program and you would certainly be eligible based on your credentials. HBS loves leadership, so you would need to play up the leadership experience in your profile. I like that you have some unique twists in your background (international, female, film student minor), yet you also have some quality work experience at a very impressive ad firm. Maturity is a big deal for 2+2, so make sure you have a clear vision of what you want to do with the MBA and where you see yourself making an impact. Your marks are good, but I will warn you that you will be up against some of the best, highest achieving students in the world (4.0 GPAs from top univeristies and 750+ GMAT scores). Having said that, you have enough uniqueness in your profile to think you'd have a reasonable shot. Good luck.
