What is the reason for rejecting this fotos

Technical issues! Your pictures exhibit many technical issues that can be seen even without looking at a full-size picture. A potential buyer would not be happy with your pictures...

• Chromatic aberration.
• No details.
   

  The example here should be crisp sharp and contrasted. Instead, you have washed out colours and no contrast.

• Bad exposure.

For the street view with the people in, you would need also a model release from all the people recognizable in the picture.

Some of your pictures have also a bad framing:

• The second has that huge obstructing roof in view,
• the first has those light pole in the foreground with the tip cut off and the body obstructing the view. You obviously took the picture from the one and only point of view without considering a nice composition. I always try to avoid such poles in the front, whenever possible. Or I make them the main subject of my picture.
