For a start, your thumbnail is really eye catching
There is a lot of enthusiasm in your voice, one thing I have noticed though is that you use a lot of fillers likes "um" and "err" which is natural, I do it all the time, maybe overtime you'll get used to not doing that so often
You also do talk about the channel in detail which is really interesting! Nice quality video too! Also intro and end card!
Hope this help
PS i subbed hehe
