Well, that's trippy.
A few weeks ago I had a vision very similar to this. I tried to paint it in photoshop, but it didn't turn out as well as this. [link]
Of course it was just the shining star on the black background with the rolling clouds and big bright stars. I guess, it's not that big of a coincidence, huh?
Actually what I mean by "vision" has more of a religious and/or spiritual connotaion.
You see I dreamed that Jesus had come down to earth and the bright glow is him in the East. The cloud is his Holy aura spreading out to encompass the earth, and the stars are the people being raptured up into Heaven.
Hey, you can believe in it or not, but your painting is almost exactly what I saw. That's why it's trippy. *shrug*
