i think you have as good of a shot as anyone... just make sure on your remaining essays, you really drill down the "why you want to go to X school" portion of it. usually it's not recommended that people apply to more than a handful of schools, because the quality of the essay and overall application will start to deteriorate. also, they don't usually have a real ranking as to what school they would prefer going to - they just apply to all of the "top" programs and hope to get in somewhere.
if anything, i'd recommend you closely look at your remaining schools, and see if they would be a good fit for you. if you find that they're not, then don't apply there, and instead focus your time on whatever schools are left.
