I think a better title for the bench view would help.
Maybe Rocky Island bench view???
That is not what I know as a pocket park. Pocket parks are small and not open grass.
It will be a hard sell but see if there is evidence on the council website for this green space,
But you have other good options
The footpath sign - nice close up of arrow would work well but need to see it - presume it’s part of heritage trail.
Footbridge is part of heritage trail and is a good candidate. Get a nice clear picture of the bridge and information about what you will see on paths. Etc
