I’d be happy to call it a haiku.

Summer in battersea park

picnics and cricket

and two names in bark.

It has a strong seasonal reference, although we don’t need the season mentioned by name because picnics and cricket place it in Summer so well.

As haiku aren’t 575 constructs in English, only Japanese, this works well as we have the first two lines as a phrase giving us a great general picture, and then we zoom into a specific close up image.

I haven’t heard an update about the book, is it now in print?
