Hello there Hildandia !
First off I just want to say that you have a very wonderful voice! So I think you already have a great start on the channel just with that.
I can’t really say that I am an expert at Music channels (I hope that I got what you are aiming for at least), but being a youtube user for quite some while now, I defiantly have a couple of subscriptions with various singers and musicians that I like. They have all have their strengths and weaknesses but they also have many things that they do in common a lot of times and here is where my opinion comes in.
While browsing your channel I noticed that a lot of your music contains a static background while the audio is playing. I’m not saying that this is a bad thing, but youtube being a largely visual format, I think its important to have something interesting going on in the video to lock the viewers attention. From what I have seen from other channels, most people seemed to remedy that situation with face cams, and personally I think this is a really great move, since it gives a face to the lovely voice who is singing. But if your too shy or do not feel comfortable or do not have the necessary equipment to do such a thing there are other options to make or request a personal moving background from someone.
I hope this helped a little XD, if you don’t really think this is good advice you can completely ignore it as well, I’m more of a graphic designer then a musician.
