Well I've got nothing against fun and kids (though as a father of six I do think their pleasures can be overrated
) but there are times when it's nice to attempt a passibly realistic photograph. In 1:22.5 scale I don't think anyone comes close to Preiser. In 1:20.3 and 16mm there are possibly a few other makes that are pretty good. I have a couple of Schleich figures that are very good value but they are over size so cannot be used alongside the Preiser.
As others have said, there are a lot of other jarring factors to contend with in the garden such as fences, flowers and clothes lines but sometimes a couple of quality figures can assist the scene.
These comments are only relevant to photographic realism as opposed to realistic character where caricature figures such as Busybodies and Jon's come into their own.
Anyhoo here's 4 pics which show Preiser figures adding to the scene IMHO, although the driver of Treasure Girl in the third pic is a modified Schleich blacksmith.
