Nit picking...
Trouble is, now the Moon/Sun relationship is not consistent with the phase of the Moon (The Sun is ALWAYS in the direction the bright side of the Moon points). In the Geometry shown, the Moon should be a near-virgin crescent pointing at the Sun.
Also, most of Earth should be in shade unless you postulate that the Moon is a foreground object illuminating the pre-dawn Earth with full Moonshine. I think this is what Marcia had in mind, we just need to change the Moon.
Sorry, both bits are pretty but they don't match.
