Well, there is a lot you do well, and a lot you can improve on.
The music is nice, a bit loud since your not projecting your voice. The video is short and was straight to the point. The content itself was good, with the script being concise and the visuals great but not too distracting. I believe the extra graphics you used (the sun, the objection guy, etc.) were all nice choices.
One pretty major (in my opinion) problem is that you exported your video at a weird aspect ratio. Either that, or you did something to garner the black lines on the side of your video. This shouldn't be a problem because you're working with graphics and not a webcam or anything of the sort. I feel as though with the background music you restart it at points, and that gets distracting. The movie's audio is louder than you so you need to lower that in future videos.
Also, this is just a personal preference, but since the clips you shown didn't have its own music in the background, you could just leave the background music playing. Also you say certain soundbites ("Precisely" , "You need this film in your life", etc.) which would have a better impact without the music in the background, or if you so choose, then you would want to emphasize that in your voice. Remember, as a reviewer, you are a curator and you want your choice to be considered. So in a way, you're persuading/informing, thus you need to make sure whatever your main point is, they take that away primarily.
