I just had a look at your channel and I really liked what I saw. I think you made a very special intro video. I was compelled to watch it in its entirety. It was very real and profound, I love that. I also watched a couple of other videos and they all shared that integrity and intensity and compelled me to watch them till the end. They were quite beautiful. I am not sure if I would change anything to be honest. I mean I didn't see anything than really needs changing. I did notice some small stuff but the funny thing is that all the small stuff seems pretty insignificant after listening to your stories.
The main small thing is that from a first look at the main page it is not immediately clear that you have a chronic illness, while it features quite prominently in your videos.
From your intro these words really stuck: “Chronic illness... The world through different eyes” Perhaps you could include something like that in your intro and banner.
Another channel popped into my head while watching yours. You can find it as AmputeeOT. I don't really know why I tell you this but perhaps you can take a look and get some ideas. Although that channel is different because she deals with a disability and one that is clearly visible.
But to be honest, you have a lot to tell the world and you do it in a beautiful way. And that is really all that matters.
Good luck to you and your channel.
PS, It would be cool if you would want to review my last video. It is something totally different though, very light hearted, not serious at all.
