you read it quite smooth but it is better to have more animation.

i agree with Nordo, if you can add some animation into the vedio, it will be much better. however, your words are very clear and not much grammar mistake, that's really good.

a. Clarity of message
Quite good organizations. And it is clear at all as you give the suggestions one after one effect/phenomenon. Good pronunciations.

b. Persuasiveness
Good opening that can attract audiences to keep looking.

c. Quality of evidence
The phenomenons you are talking about is quite suitable and close to the reality.
d. Visual and audio elements
Rich pictures but it would be better if you can have more pictures/ background music.
