Dude, I've been listening to this song all week after downloading it as an after thought while flying through my Favorite artist list. All I can say is WOW. I have to agree, one of your best ever. Absolutely love the melody, Your orchestration is awesome. Loved the change in chord progression at 3:00; a chord progression you don't typically use, but that made it even better. The syncopated Saw synth at 3:28 Gives me goose bumps every time, you are soo creative.
My favorite part is the last rendition of the melody by the square/saw synth starting at 3:44. That, combined with the alternate melody from the sine/saw synth that's been carrying the melody, make a great polyphonic ending to the song. Love the end at 3:56 and 4:10 where the two melody call and response on the root octave.
....Dang, the only things that could make this song any better would be maybe adding a key change and having a slightly more riveting intro (the beginning bored me a little, but I quickly forgot that).
Other than that all I can say is great job, and I SO, wish I could write music like this. Congratulations on another fantastic job!
