Hello and Welcome @TzioGeo
It is a very frustrating experience if you are trying to improve an area for a better game experience and your nominations are repeatedly rejected. Thanks for raising it.
There are different elements here that I will try to unpick.
First the distribution of pokestops/gyms and powerspots is highly variable. That reflects how it was originally designed - to reflect real world locations.
If I have understood correctly your immediate area is mainly residential? These are places throughout the world that can be hard to find real points of interest as they are nearly all peoples homes. There has been recognition by the game developers that there are places where they would like to put more in the game. See this article for something that is ongoing
So the game developers are aware and looking at the situation.
Your second picture is a highly unusual situation. Try not to compare your place to somewhere else. But do try to make the most of what you have.
This is where wayfarer comes in and where the community here can try to help.
If you feel comfortable to share your broad location we can have a look and make suggestions.
If you can share some of your nominations that you would like to understand what the issue is please post them in full - both photos, all the text, location and reasons for rejection - we will try to help explain and if possible improve.
