I guess I'll leave an NGADM review here since you're on Review for Review also.
First off, since this is a classical entry, instrumentation. I like most of your choices here. The piano fits the beginning very well, as well as the strings that join in just afterward. Overall you've picked your instruments well. I especially love your choice of glockenspiel in the ending! There are some things I could complain about, though. I feel like the guitar introduced at 1:05 kinda breaks the atmosphere of what was happening thus far. A different instrument might have been better.
Melodies. Man, I have to say something about these melodies. They caught on the first time. Rarely ever do NGADM melodies catch on the first time for me. That's awesome. Also I swear in the section at 1:55 I know that tune! I don't know from where, though. It's familiar.
I can't talk about mixing since I don't know how to do it but I'm sure you're mixing is fantastic!
Atmosphere. I've already talked about how the guitar at 1:05 breaks it a little bit, but other than that you have a great atmosphere going on here. I didn't imagine a "journey home", though. I imagined the adventure after the adventure, that feeling you get after you've gone on an epic, successful journey and another one comes up. But regardless the emotion in this track is marvelous!
My only real other complaints other than the guitar at 1:05 which I have been stressing far too much (sorry) are 1, the guitar squeaks near 2:33 are too obnoxious IMO, and 2, I felt the piano riff at the beginning could have been more dynamic.
But other than that you have a REALLY solid entry! 5/5, 9/10, good luck! Now it's my turn to get on R4R...
