A tough one...
While I gave you a 5/5 for your experimenting and chance taking with this piece. I respect that a lot.
The problem that I have is the wind against the mic while recording the other sounds. I've had this happen to and almost ruin quite a few of the videos I shoot for Blackstone Carp Presents. I've found that getting some sort of muffler on the mic, a fuzzy foam of sorts can really make the recorded sound crisper while blocking the muffled "Foooof" of the wind. A really noticeable one can be heard at the :23 to around :27 or so mark, but it happens a few times.
I also notice at times an odd sound against the mic that typically happens while moving the camera or mic around, like bumping the mic against your hand or something. It detracts from the over all enjoyment of the other ambient sounds in my opinion. There are a few of these as well but a good example is the :09 mark to about the :12 mark.
Aside from that it is an interesting attempt and idea and I think it could grow into something nice.
