#1 is difficult to get right. There are some regions that are burnt out. If you get a camera yourself a slightly darker exposure would be better.
The other 2 contain a mass of dust / dirt on the lens.
The bottom part of the photos should be cropped off. It doesnt add to the pictures. You'll find the composition improves a lot by cropping that off. Too bad they're both littered with dirt on the lens as both are quite nice 👍
