Children of the Night and Day

This idea came from somwhere around nowhere, like many ideas do. i cant recollect any inspiration for it-just a little corner of my mind that hasnt been interperated yet. i pondersd how to make the shaddows have some sort of unity and partenership in terms of movement in the composition (where they-the shaddows-are casted and how they direct your eye) when, out of nowhere, i felt that the sun and the moon should be the same light source for this little land, transforming from one to the other only by the bubble sepparating the night and day. the kids are naked, i don't know why.
