2 storylines!
You know when you look at the picture ,there are really two story lines going on here.One large and one small,literally!
One is large and obvious,the airplane of course ,and the other more subtle and hardly visible ,the dog that the lady in the next yard has on a leash ,much to the delight of the young girls watching.The gentleman building his airplane doesn't even notice as he is too absorbed in his "dream." The boys sitting on the fence seem to be more interested in the airplane ,as they have obviously been sitting there for awhile, but for some reason seem to be afraid to approach too closely.
These are elements that I saw or thought about when really studying this picture.That is why I think that this will make a great diorama! The imagination is initially captured by the airplane and the clothes on the clothesline ,which seems totally out of place until you realize that it is somebody's backyard.Once the attention of your imagination is engaged then all the other sub-stories can be told.To me this is what makes a great diorama ,not only to capture the viewers interest but to hold it long enough to tell an even more subtle story.
We dioramists don't have the luxury of language to tell our story but we do have imagination!
