Hi Richard, I thought there was some great stuff in your trip report. The best bit for me was the close-up of Tryfan - pity you didn't get someone doing the leap between Adam and Eve - and then the cantilever stone bit at the end. I really liked the way you cut that, and genuinely 'lol'ed at your bounce - you should definitely have done a star jump!
Great views, lucky you!
For constructive criticism feedback - I can't give you anything really on the filming, though it must have been tough doing it all solo, but here's a few things:
Try to avoid starting every sentence with 'well'
Water is noisy! If you can do something about the balance of the sound that would be good.
The intro music was great, and I liked the background music - at least for some of the time; I found I'd have liked a bit more variety as the video went on.
Maybe a look at a map at some point so your audience can see where you're going. I ran up Memory Map to see where you were going, but not everyone will be able to do that. One of my undergrads last year did an awesome little powerpoint slide showing Hannibal's route round Italy during the 2nd Punic War with wonderful elephant's footprints appearing on the map to show Hannibal's progress.
I hope you don't find this off-putting; I genuinely liked your video and your presentational style and with a couple of tweaks it can be excellent. Let's have some more!
