I am probably not the best person to give advice but it will start getting easier for you after a couple of videos. when i watched your video the first half of your video it felt like you were reading off of a script and made very little eye contact with the camera. then when you started talking...
The 5100 is gonna be my next vlog camera when I can afford one. The flip up screen is a major selling point for me and it's almost half the price of the g7x.
Try to make at least one new video a week. The more videos you have the better chances you have of people watching them. Most of my content only does well for the first couple of days.
