Hello and Welcome,
From the info you have given I am guessing you have nominated the “Windmill Mural”.
IMO: This does not look official and would therefor be classed a Graffiti and I would have Rejected. I am not local so will not get to vote and local reviewers may have a different opinion.
The land in the middle does have an Outdoor Gym which is in a separate cell to the Children’s Play Area. This should be an easier nomination. The Outdoor Gym and the Mural would share a cell so only 1 would be able to be a Stop / Gym.
If you are not aware of the S2 Cells system used in Pokemon Go please read the following… https://community.wayfarer.nianticlabs.com/t/why-an-accepted-wayspot-may-not-be-used-in-pokemon-go-s2-cells-and-pokemon-go
Also noticed that you mentioned “Intel”, if you are asking about something in Ingress it is no longer part of the same company as Wayfarer and Pokemon Go.
Please ask any questions, you will get help.
Good Luck.
