I have found 2 key factors that are important and haven't been mentioned, for stills.
The most important is minimal wind. The drone is remarkably stable in a steady breeze but not so good in gusts, even gentle ones if you need a long exposure of more than 0.5 second.
As my pics below, to improve your image sharpness in less than optimum wind, consider a more distant shot. The logic being, the small movement of the drone becomes miniscule in the image at greater distance. Of course, you chose a closeer scene and there is nothing wrong with that, if the drone is rock steady. I thought you did well with many of your shots.
The other big issue is, how much light is there in the scene? In your shots, there is a lot of large, intense lighting. In mine, the lights are just pinpricks, generally. Because of this intensity, no camera can cope with it. There are some options open to you. May I suggest a trial shot in auto mode just to get a feel for the settings you need.
1/ Bracketing would be viable, if you have little wind and are able to use an image editor. For users who don't know, in this mode, several still images are automatically taken in succession, each with a different degree of exposure. You can adjust the difference between the exposure before you shoot. Try with the default setting, typically 0.3 and increase this if you need to. The idea is to expose correctly for those large, bright areas, the rest of the image will be under exposed. The last image will be correctly exposed for the darkest areas and the lit areas will be totaly white or 'burned out'. The editor will combine all these different images, there may be 3 to 5 of them, so the image has a uniform exposure with everything just right.
2/ try using HDR, because this also works on a similar basis and is done in drone. You might try this first, in auto mode just to get a feel for the settings you need and also be able to review the result, whilst you are in the air. Option 1 is the more pro solution in this sort of photography.
If the drone is capable, do image editing with the RAW file, because there are tools in the editor that can transform underexposed images. A JPG image has been processed and compressed, so it looks great from the camera, but there is little you can adjust later.
Night shots are prone to clumpy detail and looks like blurred grain. It is referred to as image noise. Everything is against you when taking night shots, more so with a drone, because it moves when hovering so a fast shutter speed becomes necessary. The ISO needs to be higher than desireable for the same reason. A land based camera has the luxury of a tripod to solve the problem.
I hope this helps you.
