Hi there,
First off I'll start with what I like about the video:
The Intro is great; perfect amount of time for it, and some catchy music to go with it, you've done really well with this. I'm sure I'll remember it. Also, I found your style of vlogging to be very user friendly, trying to interact with the audience a lot - these are the signs of a dedicated and (with time) great you tuber. Well done!
However, one key thing that I would point out is the camera angle/shot. You have taken the whole of the vlog as a medium shot (showing upper body) yet it cuts off the top of your head. You should bear in mind that all of the top youtubers who create vlogs, ensure that you can see all of their head (and more background if needed). I really recommend getting to know your camera as well as possible (know it back to front), this will help when positioning the camera (so that you know its' field of view). Also, you should try playing around with the camera angles that you use; instead of a medium shot, you might want to take a long shot or the same shot just from a different angle - the side. Most youtubers nowadays have a separate vlogging channel as well, so I recommend just to look over the content that they produce for a bit, so that you can try to replicate it into your own videos.
Moreover, I would probably say that the lighting feels a little yellow, maybe try putting something around your light source to focus the beam of light on you (almost like a spotlight); it will give it slightly more mood.
Also, unless you want to go for a clean background, try putting a creative looking wall in the background to make the video more interesting to the eye (I know vlogs are about the content that the person is talking about but I feel that people may find more interest if there are bright colours, words and shapes to look at also).
But overall, I felt that this is a nice vlog, you should keep up the interactivity with the audience and your enthusiasm to the subjects that you are talking about, it will really help you to keep motivated in the future
Thanks for subbing
