It got disapproved for several reasons.
1. It is black and white.
2. It is very noisy.
3. The highlights are overexposed and the shadows are underexposed.
4. The horizon is not level.
There are also some IP issues. Logos that can be seen. I also assume, that if the exposure of the person in the wheel chair was made brighter, he may also be identifiable.
In some countries, Germany for example, it is illeagal to photograph persons that are in an emergency. For instace disabled, homeless, beggers. This might even include people shopping at a discounter because they are down on their luck. So, show respect please.
Ralph enumerated all the technical and IP issues, but I wanted to add that street photography such as yours is rarely going to be acceptable to Adobe Stock because it's nearly impossible to capture a scene that doesn't have recognizable people and signs/logos. And also the ethical problem of trying to commercialize an image of a person down on their luck...
I think a model release would certainly be needed, because the person in the shot could identify themselves, not only from their appearance and situation, but also because they would be very ready to remember the exact location, the bags they were holding etc. etc. I agree the ethics are complex, but a model release would take care of the legal aspect, since it allows the person photographed to give or deny permission, and to negotiate a suitable fee.
Some agencies accept "editorial" pictures and might accept this without a model release; it could be used only in a news story to which it is relevant (would not matter if the viewpoint was "terrible plight" or "awful decay"). However, Adobe are not in that business and do not accept that kind of news photo.
