Very nice. Congratulations.
Suggestions? If you had, say, a friend, their head right behind the camera, and then you are 'talking to them'. it might help you to be more 'natural' in front of the camera. and eye contact would seem to be 'to the viewer,' rather than the eye wandering you are doing (no 'sense' in looking at the camera as the point of interest for your eyes?) .... even a picture perhaps. or a mental realization it should be like speaking to a friend... The picture could be a reminder...
Color saturation is down. the color should be 'up slightly. Since the only thing in the video with any color is your skin...
Good verbal connection. no wandering and in particular no using the killers of umm or ahh .. none of that... which is a real major plus!. so the story line is captivating enough for audiophiles..
When you move your hands in gestures, fine. but sometime you are gripping and regriping the armrests.. better to just relax your hands then.
Great effort, hope to view more...
Good luck
Added: watched the revised video. yeah, better. the endless odd grey stuff in the background is blacked out. good. Color way better. Sound better.
