A few thoughts. I only glanced through it as I couldn't understand the story (as you warned.) A lot of the shots look great. Good composition, most have good lighting. Most of the interviews look good, and have great audio which is important. A lot of the B-Roll during the video is great. But some critiques: The titles look very amateurish to my taste and the intro is too long and doesn't have much of anything to do with the content of the video (as far as I can tell). Some of those timelapse cut in with the B-Roll from the video, plus maybe a couple shots from the interviews, I would have liked better. At about 30 seconds I was wondering if I was going to watch (or not watch) 22 minutes of timelapses.

But those critiques aside, it looks like fabulous work. I'd really like to go back and watch it with subtitles if you get the chance!

Well having understood and appreciated your piece perfectly, I find it thoroughly professional throughout - and almost broadcast-able: (a TV audience would probably require an abridged version), whereas locals will enjoy every bit of the detail - and I think it is more of a promotional genre anyway.

What could I add to improve on the well-framed, well-lit interviews and smooth use of B&W stills? Possibly a written paper which a narrator could present. Perhaps another intermittent theme with more movement to bring the story alive (Like the kid climbing down from the apple tree). Still, I think you've got some old folks talent and made the best of them. Congratulations!
