Welcome. Thanks for sharing your still image. As a landscape photographer, there is some work to be done in this image. I'm use to post processing images in PS CC. Disclaimer: I've a first time drone (
M2P) for about 2 weeks, so I'm still riding the learning curve. However...
My first thoughts are:
(1) Learn the various settings in the controller. Take a walk through numerous YouTube videos on this subject that also include camera/video settings. Like with a digital camera, you will need to learn: Auto vs Manual (Personally, I always go with manual mode.) ISO, White Balance, f/stop, etc.
(2) What post processing software do you own/familiar with?
(3) Need to focus on exposure and shutter speed. There is a balance in images between overexposure and exposing in the shadow areas.Those areas are pretty straightforward in your image.
(4) Myself, I would have also shot an image w/o the sun. Swung around to the left and focused the exposure level on the town. Or, wanted for the sun to go down a little more.
Hope this gets you off in the right track? Others will have more suggestions. Look forward to more of your images.
