That image looks pretty sharp. In my opinion there are three categories to master and each one takes time but with time and patience almost anyone with a desire to learn can do it.
First, fly the drone and familiarize yourself with the GO4 app, it numerous settings and features and there are endless. Second, after you are comfortable with all of that you can start to figure out the best settings and techniques to shoot a photo or capture video from a flying platform, again there numerous settings and features for both photo and video. Third, after you capture the photo or video you can begin to edit it with whatever software program you are familiar with. (ie. Final Cut Pro, Premier Pro, DaVinci Resolve, etc.) again all this takes time depending on each of your strengths and weakness for each category. (1.Drone Flying 2. Photo/Video Capturing 3. Photo Video Editing.) From a scale of 1-10 I rank myself as a 7-5-5...lol
