Ok I watched some of your videos and I'm a bit confused. Are you doing a character, or are you just hiding your face and changing your voice because you don't want to be recognized? If the former, then I want to see better lighting on you and definitely another background that fits your character way better. If you however just don't want to be recognized then I see no point in having a facecam. Maybe you should go with only voice? Do you see what I mean? Whatever you do, do it all the way.
The videos are also extremely low energy, speech is slow and emotions non-existant. You want to move people and that is hard if you don't express emotion. One trick is to not do videos when you are tired or have to be quiet because of parents. Show your viewers respect by only recording when you are fully able to perform.
Also I cannot read the text on you banner. The colors blend too much into the background.
There's unfortunately not much else I have to say. But I hope that helps at least.
