First of all, I really appreciate the review on my track.
Second, I'm warning you that this will be a long review.
Intro: I love the very slow, building intro. It's gorgeous and effortlessly builds tension, urging to listener to stay and wait for the big finale.
"Verse": I like the bass line, but I'm sorry to say that I don't like the synth you're using. The kick is very tight, don't change a thing! I love the various additions you start to slowly bring in, especially the arp! The synth that follows, adding a percussive essence is an excellent addition as well!
Down Tempo: Again, I love the pad you've chosen. Though I must admit, it sounds far too "preset-y". That bell-like effect in the background sounds almost like a high-passed piano with tons of effects, if that's correct, then props to you for thinking of it! Clever! I adore the synth that comes in after that, though I wish I didn't fall so far behind the pad at times.
"Verse 2": I don't like the way you rushed into this section. I think a more tense, yet natural transition would have been better. I also think that adding more to this section (like the elements that came in with the previous section) would give this a huge trance effect.
Overall: This is a fantastic track, I'm really impressed with the mixing! Everything stands out very well and you've made the 6:00 length listenable, rather than something that just constantly drags on. The biggest things I think you should work on are the second verse and the synth for the bass lines. If you decide to change these things you'll earn my five stars.
If not, well... Free five!
