Some constructive criticism;
I'd recommend getting a better video capture device. Its almost impossible to tell whats going on in some of your videos because the quality is so low, and because you are also difficult to understand, sometimes its hard to find a redeeming factor.
Articulate yourself as best as you can. It can be difficult to hear you during your videos, so making sure you pronounce words very clearly is key.
Focus on having a theme to each video with a relevant title and thumbnail. The title, thumbnail, and theme to many of your videos are all seemingly chosen at random.
No other feedback that I can think of atm.
