Your videos are all very professional productions and there is nothing wrong about them. Each of your performances was clicked between 800 and 4000 times, you got 1000 subscribers and quite a lot of positive comments. Taking into account that nowadays people are uploading 500 hrs of content each minute (!) on Youtube, I think that is already a lot. I wonder if you should expect much more. I have listened to some of the samples of your new album, and I must say your style is nothing special. I do not mean to be negative, see above (there is nothing wrong about your music), but I play piano covers myself and I just like my style better (if that is allowed). But that does not count, and talent is the least thing you need to become famous on Youtube. There is so much trash out there that gets attention from a large primitive audience.
