You have an interesting background. However, it is difficult to assess your chances based on such limited information. Much of the admissions decision is based upon essays, LORs, and interviews (once you cross the basic GMAT and GPA hurdles). Your GMAT is a bit low however it is still within the acceptable range of the schools you listed. MBA admissions is very competitive at this time so you need to really market your experience and differentiate yourself from the rest of the applicant pool.
