Your filming really made me bored. It was the same angle every time. Try switching it up once in a while, and also switch the background to keep viewer attention.
In addition, try editing out your trip walking back to the camera. It seems really unprofessional that you are doing that, and shows that you put little effort into editing.
YoYo videos aren’t just about tricks, but are also about filming, editing, etc.
And I totally agree with Samad’s comment above. I try to make every video (that isn’t a tut) interesting. Presentation is a big part of the video, and while your tricks were cool, I was kinda bored.
