Oh pretty colors! It almost makes look as if this is where the ghosts play, and the ball of light in the center is the place where all their energy comes from! Good job well done, and it's chaotic in a off sort of way.
How interesting. I can see ghosts floating all over this image - I can even see some faces :) I agree that the bright light in the middle is sending out vibes to these ghostly beings. There's a lot of chaotic action, swirling and twirling going on. The muted colors work well with these spectrums. Good job Dave!
