Time to get my reviewing ideas out.
INSTRUMENT CHOICE
I have no complaints with the instruments -- they are real-sounding after all.
GENRE
This song still has a part-electro vibe. If you were aiming for orchestral, this could technically fall under Cinematic, because of how epic-sounding these things are.
MUSIC ITSELF
0:00: Sounded like a soft intro, except for the electro-sounding cymbal roll. A cymbal with a lot more decay could've been used for authenticity. We will also take this as our proverbial A-section.
0:59: Counter-melody could've been appreciated here. It would accompany the harp, because a single line of the same note slightly mismatches the epic feel of this piece. Let us take this as our proverbial B-section.
2:08: A crescendo would've been appreciated here, rather than the silence. My understanding is that you're building up to something louder and more complex.
2:11 brought back the main theme beautifully.
2:44: This blend of electro and orchestral here is splendiferous, to say the least. <3
3:22: Back to the theme of 0:59 I see.
3:52: That loudness, and then the introduction of a softer melody, that was well done.
5:00: That silence again was not necessary -- you could've smoothly transitioned to 5:08, piercing through people's hearts as you would want to.
5:39: Again, 2:44. <3 A bit more instrumental buildup, something in winds or percussion, or even harp flourishes, would've been much appreciated here, to essentially tell people, "THIS IS IT. THIS IS THE CLIMAX!"
WHAT COULD'VE BEEN USED HERE
I agree with Kajenx that the song was a bit repetitive. The melodies certainly had potential -- what I heard in the A-section was memorable, and I could sing it after having listened. This song, as I hinted earlier, seriously could benefit from counter-melody use.
Another thing that could be of use is a "bridge" of sorts, a proverbial section C. You have an A-B-A-B-A structure, which makes it repetitive. A-B-A-C-A-B-A would make it a rondo, which would already suggest you've mastered an orchestral form. Also, it switches things up. In that bridge, you could take liberties with key changes, chord changes, borrowing previous melodic themes and adding more original melodies to make it distinct. Musically, I felt this was sorely needed.
Mixing could use some work as well. The instruments sound like they've been panned alright, but we could use some reverb and decay. Now different instruments will have different levels of decay, as you may be well aware. Try to imagine, say, a Super Mario Galaxy song playing in your speakers, and compare and contrast with this. Hopefully, you'll be able to add whatever decay is necessary. No worries, I've been there before. ^_^
Also, I agree with Kajenx about the compressors -- I used to compress my works a lot, so I've been there too. Thing about compressors is that they seem to bunch all the instruments together in a small space, and you can hear that when the file's been exported. If you have to use compressors on individual instruments to avoid peaking, do so -- but do so as a last resort. I trust you'll use better judgment and not compress the whole piece.
FINAL REMARKS
You have done some very solid work with this piece, but the kinks need to be knocked out. I must assert that you have a winner in the works -- and I would really love to hear this piece once more, once the changes are implemented!
3.5/5.
