Nice review. Went smoothly and effectively. Though you tend to say uh and um a bit between sentences. I know that it's a hard habit to break, but for advice, if you're trying to find the right words to say, just stop for a second. It will feel awkward since you may perceive the amount of time of your silence to be long, but to the audience silence can be a good thing. Especially since you talk rather fast, so stopping once in a while to let the info sink in the audience's head is okay. It's more awkward to hear someone stutter than to just hear silence for a second or two. I'm no reviewer myself, but I do quite a bit of public speaking at school. So hope this helps in your future reviews!
