I liked it, but some parts were worse than the rest. I didn't like when you showed the pictures of the electron and neutron, looked like you just took a random pic from google.
Lol, next time someone tells you that life without religion is boring and that it's silly that everything just "popped" into existence, just show them this video, lol. Not saying that science > religion, because personally I don't think they should be compared at all, but you know, you'll always get at least one person telling you that science is wrong despite having nothing to base it on. Go you little protons, go!
You should create your own pictures for the proton/neutron, it wouldn't be hard. Other than that, very nice!
