I really like this vlog of yours :) It was very well-made
Your voice is clear, the animations went pretty well with the video and I didn't necessarily have the feeling that I was starting at the exact same image for ever. The idea itself is also not toooo boring so you can kind off keep on watching.
One of the biggest downsides (and) upsides of the video is probably the length. Well.. there are some people who love longer animations and really appreciate it, but I think that most of the people like to keep it short and straight. I would suggest to make something up to 6 minutes, unless you want to make a special video that's a bit longer, this is of course fine.
Also, a bit mOrE animations that go with the video would be appreciated.
Anyways, I hope I could show you the unique sides of your video and also some of the downs. Just keep going and creating animations, you seem to have a lot of potential! ;^)
