First off I'd like to address it's great you have confidence in yourself and that you took the time to disclose how you felt about your own pieces.
I need to address a few things that bothered me, though. First off the quality of most of your work is amateur at best, and you seemed quite convinced you had placed before us a masterpiece of inexplicable grandeur. I don't want to debunk you're enthuisiasm, though. Your willingness to talk about how you felt and why you did things with your works is a quality that many artists lack at your age(albiet I'm younger than you, but maybe that proves something).
Again, nothing wrong with your confidence, you just need to be aware you haven't achieved the level of potential you described here.
