I'm not so good at reviewing vlogs but I have had a look and have a few things for you.
Channel:
The main things I think you should do is get yourself a background or make one yourself, choose or make something which represents your personality and yourself, perhaps something like the wall (door perhaps?) splatter painting as you seem to be very creative. I would also add some information to your About Me section, your current one is very short and doesnt really tell us much about you or your videos, even just describing what your videos are about in general would be better but of course add some of your personality in there by all means.
To make sure you get as much attention to your videos as possible make sure to redirect people to your featured tab rather than the feed, these guides show you how to do that and also how to turn on autoplay for your latest video(featured video):

Having autoplay on it is great with any channel, anyone who views your channel is viewing your video and getting you more views on whichever video is featured.
Videos:
I think the overall quality is fine but the audio seems a little off here and there, investing in an external microphone for your camcorder would help. You're engaging your audience well too with asking questions in your videos so keep that up, perhaps add a few more in where you can.
When titling your videos try and make them sound more interesting if you can, Sunday Vlog for example is used twice, if you could pick a certain thing you discuss and use that as the title that could make them better, something like Music or Computer Science - Which to choose? I think it would be good if you do some vlogs where you discuss a single topic and ask for your viewers thoughts on it, something that is part of your life perhaps and something they might be able to help with or give you some input on.
Good luck with your channel
