I'm posting a few comments on some of the NGADM auditions that particularly stuck out to me, and this is one of them!
Felt the need to drop by and let you know that I think that both your singing and mixing/recording thereof have improved tenfold since my last encounter with your music. This is the first thing that stuck out to me when hearing this track while sifting through the 200 auditions! On the one hand, it's not perfect. Things like 1:12's clipping on that high note, and some lack of clarity at 2:38 with all those vocal harmonies, indicate that there is still room for improvement. On the other hand, former problems I had with your singing (bad recording/mixing quality, iffy higher register) have all but disappeared! The singing in this is mixed tastefully and sounds crisp, and your higher notes sound absolutely wonderful now, complementing your strong lower register, instead of falling behind it.
Of course, the other things that you've usually nailed in your music have once again been nailed right on the head. The composition is beautiful, both in melody and harmony. I especially love how subtly you introduced the other instruments with the prolonged note on "autre", and how the song effortlessly transports itself from one mood to another, from a solemn, solitary and intimate mood to a truly uplifting turnaround at 1:44. Oh, not to mention the divine atmospheres you've created at the very beginning and at the very end!
I feel like the main things holding you back are your instrument samples and mixing/levelling. My advice for the contest is for you to hold on to your signature weapon - your command over real instruments (primarily your voice). They elevate the expression of your music in a way that mere soundfonts unfortunately can't do. In any case, no matter how far you make it in this contest, let me just say I think you've already come an insanely long way since the first track I've heard from you (Propter Te). Best of luck in Round 1!
