Very great job!
-The over all sound. It keeps the feel of NiN's ambient style, but gives it a different taste.
-Great tranitions. Although the beginning may need some rework, they were nicely done.
-Very interesting. It had me hooked from the beginning to the end.
-Awesome remix. It's very well done, and is a great example of mastery of one's creative abilities.
NOT SO AWESOME:
-The Tambourine. It's a bit too loud.
-The Piano. It should be brought out a bit more, and be a bit less supportive of the vocals.
-The echo. In some parts it's great, but it seems to get in the way more often than not.
-The vocals at 2:15 seem waay out of tune. Way tooo sharp. I would take an auto-tuner to it and make it a semitone flatter. It sticks out bad, and almost ruins the mood of the song.
It's a great song that has captured the essence of ambient music. It took a long time and lots of effort, and it shows very well in this song. Although some things could be fixed in a rework, it's nothing incredulously hard to do. Keep up the great work, I would love to see more in the future, maybe try "The Mark Has Been Made" by Nine Inch Nails. Although there aren't vocals, I would like to see a remix or "cover" of sorts. It would be a great sound to hear.
