All in all this is a very complete video - good quality, good editing and appealing content. All the different shots give the video a good rythm and make it easier to watch. There is a sense that the entire video is a meditation on itself and it's very relaxing somehow and I'm sure you will pick one or two tips that you will think may help you.
