Great
Good work on the piano cover - I love the halo music before that Reach abomination came out.
Perhaps you can do more?
Maybe from Halo:CE or ODST
One complaint is that the keys (melody) wasn't as smooth as I would have liked.
The intro was smooth as butter, but it seemed to stumble after that - things that are even a millisecond off annoy me (or it could just be my imagination)
Nevertheless keep it up!
