There are many vlog channels out there, and the first impression that I got when visiting your channel was "Just another vlog channel, just less popular"
People watch videos on YT either to be entertained or to be informed, your videos have to offer one of these values. Now, your videos might be entertaining, and you might be a really interesting person, but ask yourself these questions, "Wouldn't these people be just as entertained watching other, more popular vloggers' videos? Why would they choose my videos in the first place and not those aforementioned individuals'? What values do my videos have that they won't get on other people's videos?"
Then work your way from there, base your style, branding, and marketing strategy from those questions.
These are some of the most pretty generic tips out there, but I hope that helps somehow, cheers.
