This is interesting...very interesting. The strong beat and strange energetic qualities don't usually categorize this as ambient, but it is very atmospheric in a way. I love all the quirky effects toward the beginning, as well as the dark mood which is very uncharacteristic for many recent tracks of yours. The rapid transition between moods at 1:41 with the piano really caught me off guard. I think you either need to a) incorporate more elements of the first half of the piece into the second part very soon after the 1:41 transition or b) cut the part from 1:12 to 1:41 (or otherwise make it a part of :00 to 1:12) or c) all of the above. That said, I love the melodies later in the piece, especially at 3:25, but I still think you have two completely different songs here, Johnfn. I liked the ending, though. I think you could stand to work on this one a lot more, but it's mostly just structural details. Overall, it's pretty good. Keep at it, Johnfn! ;)
