I've got a lot to learn on the camera side, and since I've crashed 3 P2's (plus near dozen X4's) maybe could learn a little more on flying too. I have 2 thoughts that came to mind, In a fairly dark overcast day as the picture suggest, is 1/750 a little fast for the conditions? And from an indoor environment to outside conditions which appear very cold there, as with my astronomy hobby, I have to allow the optics to get acclimated to the outside conditions which takes time, to prevent moisture mainly on internal optic surfaces before using. And I'm not talking about dew, but very fine almost unperceivable haze. I keep my telescope, and when winter starts will keep drone also in my garage work room which is near outside temps but has low humidity. You certainly have a beautiful area for filming, good luck.
