Hi Francisco,

this is a really small park, are you sure is correct?

this as well, it even has a clinic inside

this doesn't look like a beach, it even overlaps a road

there's really a natural beach on a canal inside the city?

most of  your park and beach edits doesn't seem plausible, could I ask you why?
