Hey!
I looked at your channel and saw you missed a couple of things.
Firstly, your banner. There is nothing interesting to see there and doesn't show what you do or what you are about, and wants me to click off
Secondly, your thumbnails. They are not attention grabbing or even custom, and doesn't bring the idea of the video across.
Thirdly, Content. In my opinion, your content isn't that amazing and it doesn't grab attention.
Finally Tags. If you don't put tags, when people search up for keywords in your title or description, they won't be able to see the video as there are no tags.
If you need more advice, PM me!
