This is an amazing idea, and a beautiful execution of it, too. Love the glowing stars and the bright sky. It looks peaceful and mysterious. A snapshot from a land of dreams.
After looking at it for a minute, I suddenly wonder what it'll sound like. A waterfall made of stars. Will it rush and roar like a normal waterfall? Doesn't quite fit for me... Now I imagine a ringing sound, a soft-spoken melody, floating along with the mists made of stardust.
Yup, beautiful indeed.
