I like the style you've got for your videos. The opening with the environment shot and date is very serene and nice. I'm going to try to give feedback, but these are more suggestions.
Things to improve: Your image quality is very nice, what falters is the audio. Every now and then the audio may get loud or quiet depending on the shot. Try to keep it balanced.
You've got a sort of voyeurism thing going on with your videos, which matched with the audio and sleek videos captures an audience. What would help you would definitely be learning camera angles and framing.

Just google Camera Angles/movements and you'll get a heavy list of techniques. I don't know if you've studied this before or if you're even interested, but understanding what camera angles, framing, and movements do psychologically to a viewer can easily help you guide a video whereever you want it to go. If you already know this stuff then I say dive in. Go crazy and find cool shots. Maybe invest in a small, but good camera that youre not attacted to and just treat it like a tool. ie, put it "dangerous locations or scenarios" like the railing of a bridge over water, or strap it to the side of a bike.
Suggestions: Don't gotta follow them but they could be interesting to develop
1. I'm not particularly into Vlogs, but of the ones I like watching they tend to start the video with a goal. Even if its simple. It helps keep interest throughout the video. Even if you fail, iots still interesting.
2. Another idea is record short tidbits each day and assemble a weeks worth of footage and summarize. You can set longer goals and it can somewhat pull the strain off your shoulders.
3. Go tranquil, just completely set your style and try to show pretty shots with light commentary.
You're doing good, so keep killing it till you make it.
