Hey man, I believe the year in the narration about Bill Gates sounds weird… like “niketeen”…
Also, some things to take in count:
– I still feel that you are reading, probably this is the reason Salma felt it a little bit monotone.
– Try to add some more prosody to the reads, every read, speech, narration, promo, etc… requires some of it to make it appealing to the ear (and the brain). Also, the Anaconda narration shouldn’t have the same intentions and prosody as the Bill Gates one or the AT one.
– When narrating a documentary, you must sound sure of what you are saying, we have to feel that you are the owner of the truth about that topic (even if you’re wrong).

There’s some others, but this will be a good starting point for you to work with. Keep the good job!
