I'm amazed that on your first attempt, you made a song outside of your comfort zone that's this good! And you managed to avoid a generic sound as well.
You became really good at making your percussion and melodies work well together; I remember I used to comment on that a lot. It now seems like an area of strength for you.
This might be typical for the genre, so take this with a grain of salt, but I'm not a fan of the use of what seems sort of like white noise. I find it a little distracting, which is unfortunate because there's so much ear candy in the song. I also think that the song is ever-so-slightly over-compressed, and it creates an effect that sounds like all the elements are glued together into one wall of sound; perhaps you wanted that, but I can tell you put a lot of effort into making the leads sound highly expressive, and I think the leads would shine more if they were a little more detached. I hope that makes sense :P
Still, this is a great track, especially considering the genre change.
Like Chrono, I also love the key change.
