Here’s a quick sketch I used to quickly turn my idea into a visible image.
The man of the earth comes out of a cave and sees the spiritual light. He realizes that the world is not just dense material. Turning to the sun, he receives its blessing.
He had never seen the sun before, only a fire burning in the cave, drawing shadows on the cave wall. Remember Plato's cave parable!

I like how you emphasized the highlights with the white gel pen. And overall I really like the whole thing.
