Welcome to the forum.
We are not here to provide a free proofreading service and we simply don't have time to watch 2-minute videos, especially in this section of the forum. If you have specific questions about tone/pronunciation etc in your video script, then you can post that in the Pronunciation section of the forum. Queries about your blog can be posted (preferably individual questions as separate threads) in the Editing and Writing Topics section of the forum. It's possible that someone will have time to go through the whole thing.
