Hey I watched the video in your signature and thought it was good. I think you have a good personality to vlog and were funny. Doing anything thing repeatedly over time, of course you are bound to get better at it! I'm sure you can already look back at your earliest video and think "Oh god, that was horrible". So, just know that the very act of doing it will make you better...
When I hear daily vlog, I think of two styles. There's the style of CTFxC, BFvsGF, Shaytards, ect. where you are recording your entire day with a pocket camera. For me personally, variety is what makes these interesting. Remember, it's a video and all three of these people will go out of their way to capture visually interesting and comedic moments; wether it's Jesse and Gina doing acrobatics, Shay throwing his kids into the air, or Charles rocking it out on stage. If you've seen them, you will know they rarely have long conversations with the camera. However, when I hear daily vlog, I also think of the style of Daily Grace, or wilsontech1. These are almost the completely opposite where it's a fixed camera and they talk about one specific topic for the entirety of the video and they're usually in one location.
If I were going to watch you on a daily basis, (and this is only one person's opinion so feel free to take it with a grain of salt) I guess I would prefer that you sway more to one side or the other. I'd either rather see less talking and more goofing around, cool locations and your whole day. Or I'd rather you just put the camera down and talk about one topic and (but still being entertaining an funny). Again, this is just what I like, and what I thought when watching the video. Good luck!
