"Sunlight is heavily reddened as it is filtered by Earth's atmosphere, an effect obvious from the ground as well from space. This painting shows possible lighting effects upon the rings along the edge of the planet's shadow; of similar reddening in the sunlight filtered through the atmosphere of Saturn. Oil on gessoed masonite panel."
Compelling rendering... Although the reddening may not be exactly like what is depicted here due to the different atmospheric composition, that comes only as an afterthought. Great work.
