I don't want to intrude and make things more difficult. As it stands, your description is great.
It's just that, I think this is a photo of a girl doing an Easter egg hunt. Of course, someone from Japan may not be aware of it and that's why I was a little reluctant to mention it. But I wonder if you get extra points for figuring that one out! The over-sized basket and its colors screamed out to me: Easter!
