Great melodies, but too long and repetitive.
Overall, the melody was extremely well polished. Also, the EQ was as close to flawless as I've seen on Newgrounds. However, I think your beat's volume could stand to be a bit lower (if it's all on one channel, you could just tweak it down a bit). I found it somewhat overpowering contrasted against the subtle strings, choirs and relatively quiet 8-bit synths you chose as leads.
The transitions you had between sections were really beautiful, and this is officially the first time I've used that word to describe any Newgrounds submission. It irked me a little bit, though, that once you'd put such great melodies together you just ran through them several times and then ended the track without any real buildup. As it stands, without a real ending and with a substantial amount of repetition, I can't give you more than an 8.
If you ever decide to revisit this track for further production (and I really hope you do), please put at least one seriously grandiose ending on this, and shorten it up a bit. If you did, I'd rate it an 11.
