I understand how disappointed you are in the outcome. I was involved in a project in high school, a million years ago, in which we put together a video presentation on natural childbirth for Alaskan Natives - this was back in the early days of videotape so it was a lot of work. It was never used - but, it was a fantastic learning experience, and helped me move towards my eventual career of audio production software development. So don't fret that your work wasn't used, that's actually the way many projects turn out.
