Pretty cool, and original-ish. I liked it.
Its not ambient though.

Oooh i like the piano. The staccato playing mixed with the echo creates an interesting sound. The melodies were pretty interesting and the various instruments and sounds that appeared throughout kept it interesting, the bell certainly gave it a graveyard feel. Overall quite a nice piece, though perhaps a bit repetitive for a loop.
Oh and you should have labelled this as a loop and not a song otherwise it won't replay automatically.
