What software do you use for HDR? The photograph is a little soft, so I’m guessing you had drone movement between the shots. Most programs have alignment options to help with that. Although I bracket all of my drone shots, I generally only choose one exposure, and adjust the highlights and shadows in lightroom to get a similar look. Shooting in RAW helps keep more of this info, if your drone supports this. There are free RAW converters available. It can be a pain to deal with ghosting (objects moving during your bracketing).
