This is an NGADM 2015 review.
I really love the piano in this! It works so well in such an exciting track and is one of the most interesting elements to me in this one. What also really gets me about this track is how memorable it is, because it's quite catchy, but you're not afraid to stray from simplicity (where most of catchyness lies) and I think you've hit a really nice mid-point between the two.
So as with most of my reviews this round, it seems I'll mostly be praising the composition and instrumentation and nitpicking the mix :P sorry
So right out the gates the piano and cymbals are beautiful! The tone of the piano is really excellent by the way, I don't know why I'm so excited about that. Is it recorded or are you using a VST? Anyway - there are a few things I notice as soon as you bring everything else in at 21 seconds, namely that the low frequency sub-impact thing you have muddies up the mix a little (needs more of a transient, imo) and that it really exaggerates how I expect the chorus mix to sound, as there's more low frequency content in the first half second or so of it than in most of the chorus itself (I think I mentioned something similar in the previous round, although it could have been on another song). The other thing is that the percussion is quite quiet and lacks impact, especially the kick. The cymbals are actually pretty damn nice and airy, but I'm finding the kick and snare are a little low. The interesting thing is that later on at 1:10, it all sounds pretty great! Kick could be taken up a bit, but otherwise it all sounds fantastic. It's more in the main choruses that your percussion is somewhat overpowered.
Something else I'm noticing is that at 1:24 you really need some kind of transitional element to give the new chorus some impact, especially since the percussion in this section is quite low as well. I also am unsure about the panning you're doing on the kick. The idea is solid, but because the kick is so overpowered, when it comes into the sides it ends up being a lot more audible (especially in the high end) which creates this feeling of inconsistency for me.
I think the part at 2:10 is pretty solid, (melodically it's GOD DAMN AMAZING) though, partially because you've got those orchestral toms and whatnot. I think it's a much more appropriate pace/style of percussion for the sound and takes a more appropriate background role to the lead instruments. It also has a lot more impact and power than the kick drum in previous sections, and it's a lot more exciting. I suppose "exciting" is a pretty appropriate way to end it, and it works well :D
Sorry about nitpicking, by the way, because this is an awesome track. Great transitions, great melodies, great chords, great instrumentation. It's been a blast to listen to :P
