I love the piano

I missed the part of darkness.. I can't sense the change from darkness to light, or see where the music is moving, but it game an overall feeling of... hard to explain... it's mysterious.
The piano filling the background beautifully.
I felt the flute was too loud around about 00:37, but it can still flow well.
Very good job!

Beautiful, magical, deep.

It is a true masterpiece. There is, however, one thing I would change.
It is beautiful, but only because it is here, on Newgrounds, I would remove the thunder in order to widen the variety of atmospheres it could match.
Still, as a stand-alone track, it is beautiful and can really make me imagine what it's aiming for.
Overall, excellent job!
