The good:
- You have a natural nicely sounding voice.
- Your commentary has character and is engaging.
The not so good:
- Generally I thought the video footage could be improved a lot. My personal goal is to make the video footage so good that when you turning off the sound you still get to see something worthwhile. Especially the first part of the video we mainly get to see one shot (the helm on the table), which is not very interesting to look at for that amount of time. I would have shot some additional footage that illustrate the things you are talking about. For instance, you mention some effects of the helmet mounted camera. That would have been an ideal moment to show some footage that actually shows the effect you are talking about. If you can't come up with appropriate footage for the things you are talking about then you may wonder if making a video is the right medium to tell that story with.
- I also thought the video was too long. It was not too long in an absolute sense, but it included too much stuff that didn't really relate to your subject. At the same time I also got the feeling you missed some stuff. In short I would give some more thought to the structure of your video: Think about what it is important to talk about and realize that most people watching your video may know much less about the subject than you. Leave out unrelated stuff or be more ruthless during editing.
