why did these pictures get rejected?

Hi @fiona_1410 ,

The first image is not vertical, has a white balance issue (slightly blue) and is a bit underexposed. I believe that image should require IP permit. 

The second image also has a white balance issue.

The third image is an underexposed image with too much of a high highlight.

The fourth abd fuftg image are grossly underexposed. Details are lost in the shadows.

Best wishes

In addition to what @Jill_C said: you have issues with your sensor and it needs cleaning: 

People in the images will need to sign a model release, if you want to use that asset commercially!

These look like straight-out-of-the camera unedited snapshots. The first one is cropped too tight and the horizon is not level. The second one is cropped too tight. The third image has an overexposed sky. The fourth image has a leaning horizon and underexposed shadows. The fifth image has a noisy sky, is underexposed, and lack a focal point.
