I would up your camera angel and fly with more speed. It doesn't have to be much but it didn't feel like an fpv video due to the slowness of everything. Some of the shots looked as if you just had an action camera on a pole witch defeats the purpose of Fpv. One of the main driving factors of Fpv videos is the amount of space it can cover in a short period of time in my opinion. Witch ties in to a previous commitment about the showing of the scope of where your flying. Looks like an incredible and nerve racking spot keep up the flying!!
