The three Birdies together resemble here, the first time, a stage of lucid dreaming.
In the first piece, below, all kind of elements are drawn separately from each other with little to no connection whatsoever between them.
In the second piece, below, some of the separate elements of the first piece are melted into a single piece.
The third and last piece, below, breaks it finally down to only one element from the previous two birdies.
