No need to feel discouraged. You look great and have a great personality. To improve your content, I would take note of the following: try to maintain eye contact with the camera more. This is your audience, and when you look off to your notes, or whatever it is, is disconnects with us. I'd try and practice what you're going to say in a mirror several times before you record anything. Or, position your notes above your camera rather than to the side (assuming it is notes). Or if you have the $ buy a teleprompter. Maybe there's even a phone app teleprompter, I'm not sure. But that way your eyes will maintain focus in our direction, and I'm sure people will then feel more engaged. You have a lot of subscribers so I wouldn't feel down in the slightest, you're doing a great job. Everything just takes time.
