First off, great for you guys to be doing this and turning this project into something that will save some lives. You should both be proud of yourselves for putting so much work and effort into this.
As for the video. Only meant as constructive criticism. It's a great story and some good photos but to be honest, I found the video to be quite boring. I think the right idea is there, but most of the pictures were very similar which seemed repetitive. The choice of the song was kind of dull as well. You need either a well known songs with lyrics that will be really specific and heart warming, something that will play with people's heart strings, or a strong original score soundtrack (that has no words or lyrics)that will bring people's feelings to the surface, giving the video a whole new twist.
If you need some help with the choice of music, especially a movie score, let me know. I will be more than happy to give you some examples or help you guys find something you like.
