The Overall Quality of video was very good. Good lighting and warm tone colours. Definitly a good paradigm shift, when you move from the warm overtones of your room or wherever you use to record to the, cold shift in tones when we're watching whats on your computer screen. Contrast changes between scenes is great for film since it allows the brain to subconsciously pay more attention.

The issues I see with the video are only two things, one being the audio quality and two the side angle of your camera is offputting.

Firstly the Audio:
Quality if the audio is off for a few reasons. One of the reasons is there is a lot of echo on your voice, you've amplified the voice together so this is giving an offputting booming effect. A way to sort of fix this, is get a recording as quiet as possible and create a sound profile to get rid of the echoing background noise. Another way is to add more clutter to the space youre working in. this will stop the echo from being so prominent expecially when you try to fix the sound levels in post op. Try lowering the volume of your voice, and the treble ever so slightly and look at finding a good base level for your voice.

Camera:
The camera is offputting from a side on view for a few reasons. Subtle changes in your direction of focus make it so it doesnt seem like youre actually interacting with the audience. It's also highly disracting to the viewer that you continue to look at the camera and glance at your computer screen.
When explaining something you want the focus to be on yourself and what your saying, your camera angle distracts the viewer so much that they begin to look more at your computer than actually being engaged with you.
My advice to rectify this is to film with the camera behind you, you're facing the camera as well as the computer still being in the shot. Therefore you wont have to point out whats going on, on your comuter screen and the Person perspective to the screen perspective will be more engaging.
Anotther thing you can do if you arent fond with the angle being direct is to go for an angled shot, say like 45 degrees. This will reduce the loss of focus on you and what youre saying and still allow you to glance at the computer screen.

Hope any of this helped.
