you have a good voice, decent structuring and volume control,
but i can tell you recorded outside towards dusk as it begins to get very dark towards the mid point, and your posture doesn't look that comfortable to yourself, tilting your neck left, towards the end you correct yourself, but then begin to drift again, this is less to do with the presentation, but it makes you look off place,
my 2 biggest recommendations would be filtering out the background noise on your audio and recording with a tad more light,
other than that its a pretty good video, something beginners can use to skip all the jumbling around of advanced design and hop right into prototyping, i know i have been caught myself with this,
