* This is an official 2017 NGUAC review *
Oh man, this one. Really great talent, really not-so-great production. Into the details...
Mixing, mastering and production: This was the real weak point. Now, it wasn't THAT weak - I could hear all the parts clearly and I was able to get into the emotional space of the piece. But at the end of the day it's just a bedroom recording, and you're competing with people who have studio-level production quality.
For acoustic guitar, getting a great recording setup is a bit of of an investment, but certainly it's the next production step I hear for you. I would get (if you don't already have) a decent condenser mic (and a little interface to give it phantom power) as well as a Shure SM57. Point the condenser where the neck meets the body of the guitar, and have the SM57 a bit away from the body of the guitar, pointing at the soundbox hole. Once there you can play with levels and distances - putting your condenser closer to the strings will pick up great plucking, while having it away will pick up chords and louder guitar much better.
I would also recommend recording to a click track if you're not already. There were a couple slight timing problems.
From a post-recording standpoint, definitely play around with reverb and panning; try to add to the character of the guitar without stripping the real, raw, live sound you have.
Mastering shouldn't be too difficult from there if you're sticking with just acoustic guitar, but it's still a crucial step. Simply having a multiband compressor, an EQ, and a maximizer + limiter on the premaster will do a world of good.
Composition: Beautiful, atmospheric. I really, truly enjoyed it. Now, to nitpick!
Your main melody is great, and is a beautiful moment when you play that EM and F#M chord in the A section. Solid solo in the middle of the piece. I definitely liked the idea of the harmonics, but they weren't quite executed perfectly - a couple minor performance errors took me out of the moment. After the solo is finished and you go back to the A section, the melody gets a bit drowned out a bit by your background layer - I think were it blended well, it would work fairly well however.
My only other note is in regards to the rest of the elements of the composition as a whole - structure, texture, atmosphere, etc. The reason you didn't get perfect scores in these other sections is not for any deficiency, but that I wasn't wowed by the other elements too much. There are some great moments, but to get that perfect 10 I need to be enthralled and wowed the whole time. Rest easy though! I didn't give anyone super close to a perfect composition score. But I just thought I'd clarify.
I'm certainly looking forward to what you come up with. If you can improve your recording, mixing, and mastering then you'll certainly be a top contender. That's a lot to say for just one guy with an acoustic guitar. It's a testament to your talent!
