Hello, can someone explain what I can do better?

Welcome to the forum.
We don’t know exactly what the machine learning model that is the “automated process” looks for. When I did a Google Lens search on the main photo, it brought up wearable t-shirt suggestions. Maybe this model is making a similar mistake.
I used the Google Lens search for the translate function.
Description: Information about the jerseys of the local football club.
Could you tell me more about what this is? I don’t understand how information about jerseys would meet eligibility criteria of a great place for exercise, exploration, or being social.
It seems to explain how they are made of recycled plastic bottles, and there are different flaps you can lift to get info on a specific aspect of the design and manufacturing process. I would probably accept this in review
But you are not the OP. I need them to be able to explain why it meets criteria. I know that you understand criteria.
Ah sorry, I thought it was a translation issue!
Hi, thank you for your answer! I assessed the environment as suitable for training, exploring, or social gatherings, rather than assessing the specific information sign. Do you think that’s the problem?
Okay when I translate this, I see (and it may be translation issues)
Title:
Mainz RP football shirt

Your explanation that you were submitting the area makes what you said in the supporting make more sense to me now.
So my guesses are that the machine learning model did not recognize the shape of the board as more than just an item of clothing, which is also what the words seem to be about.
If @wooperIooper thinks this is eligible, I would recommend a resubmit. Possibly take the main photo from just a smidge back to show a little more of the surrounding area, if the area is the focus of the nomination, and include something about the area in the text. I am going to turn this over to others to help now.
It is always the POI that must meet criteria (Exercise, Social, Exploration). The area around is not relevant except for it having to be safely accessible.
This might well meet exploration criteria
This is eligible under exploration, but the text out here has has a lot of wasted potential. The sign has educational information about how sports jersey can be made out of plastic waste.
Mainz has a football club playing on the Bundesliga (First Division). The address of this street is literally at the stadium so it should be a project by the club or one of their sponsors, Mewa.
Here is the link to the project:
