If we view this as a 'home video' then it is clearly excellent.
Applying higher critical standards, as one might to a commercial piece with higher repoduction values then I would make a few observations.
There is some nasty windnoise, get a sock for your mic or cut the bass in the editor on that bit of s/track.
Some of the 'pretty' shots are excellent, well composed and shot with the camera on a t/pod, essential.
Absence of in shot zooming a relief and a common mistake, unless you want that youth tv effect.
Sound is poor, camera mic was it, a short shot gun mic makes the sound much better, can be had for as little as 100 quid, or lots more!
Speeded up bit too long and maybe too slow, but love the benny hill music, I often use it in similar circumstances, see http://www.zaskarfilms.com/filmPages/greatshagrpage.htm
Has a nice flow to it.
What about more music?
Titles? When where and who maybe.
Maybe some to camera stuff on peoples thoughts about the trip, add human interest.
Glad you dont use too many ridiculous fades, they look cheap.
Voiceovers can sound 'cheap' if not done very carefully, acoustic is a bit 'roomy' and maybe spoken a bit fast and could do with more feeling.
Sunset shot with cut to person sitting nice, but maybe sitting bloke framed too far right??
Are you a stills photographer first and foremost? You appear to have used the camera in that way in parts very well, that is why I ask.
Weekends away can be used to make a daft drama, I did this on such a trip, http://www.zaskarfilms.com/filmpages/zombiepage.htm
. Techinaccly quite rubbish as all i had was a bunch of crazy kids and a very basic camera that was crap in low light.
Here also for your perusal is a 'pretty' film i made with 20 mins of footage shot at a pretty village near where I live, I did not have my tripod unfortunately, was just passing thru in the car. http://www.zaskarfilms.com/filmPages/badmintonpage.htm
