Curtains concept look Better , you can also change curtains in next videos I had seen brown curtains in your old video that can also a better idea to make your background interactive or attractive👍
You can make your thumbnail more attractive to attract audience, that is put you on half of screen and put the singer or film,or hero poster on the other half it will enhance your views👍
And you should take care of regularity, I saw your 3 new video today I mean to say that you should commit to yourself I have to put 3,4,5 video in week regularly then my channel will grow up because it's a matter of continuity that subscriber demands, Not like post 2-4 video in a day and next video is taking much time Take some days like monday- Thursday Or Monday- wed-friday per day one song as you feel better👍
