Dear Paul,
Thanks a lot for your feedback. My expectations are inline with your feedback. Regarding the hard work i need to stand out from the pack, could you explain a bit more? Do you mean better essays or anything more than that.
Thanks for your time and have a good weekend.
By the way, I read your book on application essays, you have very useful tips..thanks again

Yes, I may have overlooked the medical camp organizing. That's clearly leadership and both relatively unusual and high-quality social impact work, so that would help you. So would the fact that you lead two engineers. These details combined with a 730 GMAT would start to make top 15 schools doable for you. Given your demographic you will still need to work hard to stand out from the pack.
Hope this helps,
