My mindset when I clicked play was that I was tired and wanted something relaxing, so I wasn't afraid of the length per se. I seem to like YouTubes in the 10ish minute range. Sometimes I put off watching TED talks because they are usually 18 minutes and require concentration. When I'm done I feel like I did a good thing, but they aren't relaxing.
And yours was relaxing. The thing I liked best was hearing from the locals. The chef and his crab seemed a little off topic for something called a photowalk, but I liked it just the same. It would have been great to see a couple crab photos close up with good lighting and shallow depth of field. They are such amazing creatures.
The thing I liked second best was the photos, both yours and the locals, which were gorgeous around sunset. Loved the drone going up to see the sun.
One thing I thought could be improved was the audio crossfade between cuts. Seemed abrupt sometimes.
I'm not sure what to think of the last few minutes where you're driving past the stores. I kinda liked it but I got a little bit bored because it just kept going. It'd be interesting to see where people bail from the video.
One thing I've never liked is when you say "grab your cameras, lets go." Watching it from home is like hmmm, wait, I'm not there, seemed a little corny to me. In this video you said "let's go" and I preferred that.
These are just my late-night tired musings, maybe everyone else disagrees with me. I'm glad I watched it because I did enjoy it a lot.
