I took Mari & Rann's pose from a Annibale Carracci painting of the Pieta. There are absolutely no religious implications in this. The image just popped into my head based off a scene in the script, or maybe it's because Mari's name is so close to Mary and Rann & Jesus both have beards. Who knows why I do what I do?
This is very reminiscent of the Pieta by Michelangelo and often a theme in art. The Pieta shows Mary cradling the dead body of Jesus. This is interesting how it shows a woman mourning the death of a man, apparently by some sort of unnatural affliction of space aging! Impressive!
I love your choices in colours, and I am fond of the painting done to the rocks as it makes them unfocused as you get closer to the edges. Really pops the characters out more for me. I am jealous of you painting skills, I wish I could do half of that. haha, love ya work!
