Think the camera should be a little higher. The angle wasn't too flattering.
As far as content goes I think that it's fine, maybe go a little more in depth when you know stuff about the topic at hand off the top of your head (ex. company history, product history, drama ect) but not a necessity all the time.
Try and practice memorizing your script so you won't have to refer to it so much.
The noise was fine and the fan wasn't noticeable.
Also one last tidbit but I couldn't see the video on tapatalk so maybe include a link at the bottom.
Overall you did great for your first time and I look forward to the meetup and the rest of your videos.
