I have some nitpicking for the vocal processing. The FX is quite interesting to listen to, and melodies catchy. What distracts me is the sibilant consonants of T, S, poppy P, fricative F, and your breath noises. You will achieve better results cutting off breaths by hand, manually ducking t, s, p, f, and others.
Lyrics are very relaxing.
Vocal mix at times is MUCH louder than accompaniment and at parts rides roughshod over it. I think this can be corrected to some extent by bringing up bass, snares, hihats just veeeeery slightly by 0.2 dB or less, decreasing reverb on accompanying instruments and other wet FX. The pads are suffering quite badly from inaudibility of the lower register.
2:07 is the worst example.
At 2:36, the levels are starting to come into balance!
At 2:58 the vocals are about 0.2 to 0.5 dB too loud. I think a more judicious compression or hand leveling may help.
Your solo at 3:33 is very nicely played but could benefit from snare and accompanying vocals coming up somewhat.
Your vocoded vocals at the end are gorgeous. Much enjoyed.
I actually think after hearing your outro that a lot of the mud and unintelligibility of the track is due to compression picking up reverb and other wet effects and giving the impression of a wall of sound. Check out 2:02 with those pads getting lost in a wall of reverb.
Your vocals sound like they're spread out almost completely evenly in both channels, leading it to sound as if there's a weak center. This works for your vocoded vocals but makes the entire track sound very flat for your lead. Recommend a bit less chorus and perhaps a very light pingpong delay.
Instrumental wise, beyond the leveling, I'm very fond of your arrangement and have nothing bad to say. Transitions are done well. The only thing I would harp on even a little is just making sure if you must use a ton of reverb, you shorten those tails, take care to mind that reverb tails from previous chords don't clash with the next chords, or simply use them for effect with a big cut off like your end. Modulation, modulation, modulation, or you'll get mud.
Beyond that, great piece. I'm suffering from depression myself, so I'm here with you. Keep doing what you do!
Thanks for coming out to NGUAC!
