coO0L ambient; i like
If I were going to make any glaring suggestion it would be to pick a more subdued snare and kick drum. The pads you lined up work really well, but you need to do a bit of EQ work, I can hear some clickyness in the background, which makes me think that it might be cutting at points.
As for the obvious tempo change, I actually really liked it. It makes the second part, while still quite laid back, sound a lot more upbeat by comparison. Nice submission.
