>MODREVIEW<
As a quick caveat, most of my expertise comes from the production side of things, and that’s how I’ll be approaching this mod review. Forgive me if I come across too harsh, as I’m just trying to pick out anything the judges might find.
Right then, first things first. That combination of horns and strings—whatever it is that’s doing the little stabs throughout the song—really has some issues in the lower midrange. I’d say do a deep and wide cut around 180 Hz or so in the EQ, or even roll off that area entirely. I’d second the notion that the samples could be improved, since they just sound…cheap, I guess, for lack of a better term. There’s not a ton of believable articulation (yeah, there’s articulation, but it sounds kinda just “there so I can say I added articulation”) in there, since they really do just sound like triggered one-shot samples. I suspect if you lowered the volume of the stabs and made a significant EQ cut you’d have them fitting a lot better, at least, since they’re kinda clashing with the kick/snare and the bassline. If you mixed the string/horn stabs better (the EQ fixes, etc.), you might be able to get away with the “cheap-sounding” samples. Also: do you have any sort of reverb on them? That might solve part of the problem if you were to cut some significant low-mid frequencies out of that reverb, too. As of right now, they (the string/horn stabs) tend to overpower everything else in the mix.
Around 1:29 or so, when the piano does its own little lead thing, you’ll want to bring it up in the mix a bit for that section. Otherwise it sounds like, “wait, there’s a piano solo here? I didn’t even notice it.”
2:00 with the unison lead—it’s a bit buried, and you could probably stand to maybe even bring it up an octave. As of right now, it’s just kinda muddy. I would also mention that it feels almost “forced,” melodically, in that it doesn’t quite fit with the source or the remix—almost as a slightly random mish-mash of notes strung together. I’m sure that wasn’t the intent, and I’m certainly not accusing you of doing such a thing, but I am saying that’s what it kinda sounds like.
At the end of the song, where you’ve got everything playing at once, it sounds REALLY crowded, musically. You’ve got dissonance from melodies playing at the same time that shouldn’t play together in a lot of places (multiples of those unison synth leads, for instance). As someone who likes to throw everything and the kitchen sink at the listener at the end of the song, I can sympathize, but it just makes a jumbled mess in this case.
Overall mix thoughts: The entire mix sounds quite crowded and perhaps overcompressed. You could probably get away with rolling the sub bass frequencies off of the song entirely, maybe making a sharp cut or rolloff around 45 Hz or so. An overall mix cut of around 170-200 Hz wouldn’t hurt either. Looks to me like your bassline and kick are trying to occupy the same spot in the mix. You can pull that off, but you might have to lower the volume of one or the other, or simply re-EQ the kick to throw more weight into the higher end of the spectrum and less in the low end. Also, make sure your snare/clap has nothing sitting where the kick should be. Roll it off around 170 Hz or so. To be clear, actually, nothing besides the kick and bass should really occupy the spectrum below around 150 Hz or so, otherwise you’ve got mud problems.
All that said, it IS an enjoyable mix. I think the little voice clips are well-placed and tasteful, adding a nice little bit of fun to an already cheery track. It's a joyous and playful song, and the overall arrangement is, I think, quite nice. Please don’t hear me tearing everything apart in a malicious manner. I'm just pretty certain that it's not going to pass the panel as it stands right now with all those production elements (some of which are a direct result of the arrangement) missing.
