papkee - At Peace:
-Oh, very tasty guitar at the start! I love your guitar work in this - if that's a VST, I wish I could use it.
-Ahhhh, similar instrument quality thing at 1:46 - those low strings sound extremely nice, particularly with the guitar up above it.
-Your overall organization of this is fantastic - it rises and falls in a very natural and organized manner, which just plain feels wonderful. Excellent job!
-I love the delay on the piano which becomes audible right at the end.
-There seems to be a bit of an odd ending to the main melody (isolated at 1:12). It ends on a passing tone to the chords, which makes it sound a bit awkward. Even if it had a final note at the end of it one step down for a conclusion, I think that would improve it a lot.
-Very nitpicky thing: I think that at the end, with the final note of the guitar, a beautiful way to end the piece would be to wait for the end of the piano delays where the guitar lifts, and instead have a slow downward strum of a chord to finalize everything.
-I think it would be awesome to have a second theme throughout this which is developed a bit. That would be awesome.
The Mixing: Oh yeah. I isolated this thing, simply because of your response to TL. Here goes!
-First, that air noise in the background of the guitar. I feel like that needs to be isolated if it isn't - and if it is, it should really be slightly more apparent at the start and end so that it can more clearly show that it's part of the piece.
-As always, your strings are a tad bit too strong - try turning them down about 5-10% lower than the rest of the instruments pre-mastering. They're starting to get in the way of the other instruments around 1:15, and get in the way of everything else far more around 2:20. (other possibility - check a parametric EQ and turn down some of the mids and lower mids a bit)
-Weird bass rumbles at 2:02, 2:19 (panned left), 2:34, 2:49, 3:07, 3:23, and 3:39. Pretty sure that's a bass drum, but... there's too much in the low frequencies from the strings already - it just causes weird interference that doesn't work too well.
-All in all, this is fairly well-mixed. The absolute biggest improvement is: TURN DOWN THE BASS TO MID EQ ON THE STRINGS.
-Also, a comment I've made before - if you aren't, try turning down all instruments to about 80% volume prior to running them through mastering to give your piece some good headroom to work with. Otherwise, mastering can and will make mud.
The Result: 8.2/10
Biggest issues are the melody and mixing, honestly. For the melody it's partially the odd ending, and also the lack of a second one. All in all though, a solid effort and one of the best pieces I've heard from you!
