I can tell how far you went out of your comfort zone by a bit, I think. The first part could be mixed better, but when it changes at about 1/4 of the way in, the way you've done most of the rest of the song is very smooth. As far as variation goes, the variation throughout the song is VERY well-done. For the 2nd melodies, I think a bit more noticeable variation could be done there, but otherwise the variation is excellent. The percussion is well-mixed for most of the song, but I still think it could use some fine-tuning in some parts, primarily at the beginning. The baseline is well-varied throughout the song, and gives it a nice, calming atmosphere. I'm pretty sure I hear some relaxed sidechaining throughout the song, which is just enough to be noticeable, but not overly prominent. Lastly, you used the reverb on very nearly everything, if not everything. That isn't necessarily a bad thing, and you used the reverb well, and didn't overuse it, but do be wary of overusing it in the future.
I said I would be holding you to a higher standard, and aside from the very minor details, this track completely fulfilled those expectations. Congratulations, and I look forwards to your next track.
