Thanks all - still need more practise with all the settings to see what works well best. And flying at night was cool! It was far easier to see the drone because of the flashing lights, too.
I am going to look at flying at night a bit more. Especially as places tend to be quieter. Bristol Harbour would, and I'm sure @twickers14 would agree, would be a pretty cool pace to take some drone shots at night.
It gets more and more difficult to think of different settings for stills, but you have done a great job. In my opinion, your settings have accentuated the prime subject, the bridge, and shown it to be strikingly beautiful. Very impressed, both by your photographic soils, and by the capabilities of sparkies camera system.
