Some critique If I may. Cut it down to the most important bits, jumpcuts work.
If you can, remove the umms and awwws (I know you didn't script this video out so it's natural to talk this way when thinking). It takes a bit of self-training to remove the pauses from your vocabulary when thinking but with more videos you will get better at it.
The genom footage seemed out of place in the middle of your talking, maybe you could put all the footage near the end?
It takes a lot of courage to put yourself out there on video, so props for that. Maybe we will see more of these in the future?
