Zoom in in this image and inspect the edges which are uneven and jagged - probably due to small sensor camera and in-camera processing. Poorly coomposed, and probably no commercial appeal. motorhome - Toby.png
lighthouse.png - focus has fallen in the plants in the foreground rather than the main subject. You'd probably need a model release for the girl.
snow mountain.jpg - same focus issue here. Artifacts in the sky
paragliding.jpg - nothing is in focus. Numerous sensor spots in the sky and water.
There are a lot of photos so I am just going to point out what I saw in a few.
First of all, lots of IP issues. No car license numbers, no advertising, no house numbers nothing that can make a product, place or thing recognizable as private property or design. Highlights are overexposed. Some posterization also to be seen.
Underexposed shadows. Halos where dark meets white. Poor focus.
