Every business school wants to stake its claim as a leader in Big Data Analytics, so your skill set and perspective will be a welcomed one. You are right, though, to be concerned about differentiation, as data analysis can be overrepresented in the applicant pool from international applicants.
A successful application is able to differentiate that candidate as a *leader* (e.g., leading initiatives at work, leading peers and more junior staff though a project, managing direct reports if applicable, being an effective leader across culture and geography and job function - for instance, leading a global project with contributors all over the world in different job functions). These are the type of things that will help with the strategic positioning of you as a leader who will stand out among other data analysis candidates.
Strategic positioning is the name of the game here. It's hard to tell you exactly what strategic positioning you should employ in your app with only the information given here (since we don't know what schools you want to apply to or what you want to do professionally short and long term).
