So originally the story was of the sun running out of her palace to the tower to find her daughter in the arms of the stars, and who faded away as she ran towards them and she fell off the tower. As she went up the stairs the sun began to rise with her. I took this and added more content to make it into more of a narrative, rather than keeping it as an interesting scene that you might look in on as it would have been directly translated from the dream. The interior of the palace, and the cyclic aspect of the Sun waking up from her own dream were the parts that I added.
I really like the colour palette, and the fact, that this sketchy style(your hand moves were rather quick and rarely ctrl+z and repeated - at least I have such impression, that means I imagine you drawing the lines so naturally that you didn't have to correct yourself to get such a result^^) doesn't really look unfinished or messy. It's still detailed and defined enough to appreciate it as finished work^^
I think it's interesting how often people associate the Moon and the Sun as daughter and mother, while, actually, the 'mother' of the reallife Moon would be the Earth
That's true, but it's a matter of perspective really. If you're personifying objects from a heliocentric universe as our own is then that's how you would relate the characters with one another, but when coming from an earth-centric perspective it makes sense that we often make such a connection between the sun and moon.
