No real specifics, Larry. My complaint is basically an overall critique on the approach. I didn't vote on Ken's posted remixes, and while they are good compositions, I personally feel they suffer from the same issues (although I am only one judge). I also pointed out these issues in Ken's last submission as well.
Ken, let me be very clear about one thing in particular: you're a good arranger, and very few people on OCR can approach an arrangement with the kind of classical/chamber-music sensibilities like you can. My frustration comes from the fact that you're essentially sending us what amounts to MIDI files run through GPO with little to no attention given to humanization and sound design. OCR isn't a sheet music site; it's not a MIDI site. It's a site for produced music. You're writing chamber music; I have a reasonable expectation that it should sound like people playing it. There needs to be expression in the performance. Only you can bring that to the music; GPO won't add that for you.
A lot of your sustained strings and very flat, dynamically speaking. The only change in dynamics I can even recall is the decrescendo at the very end of the song. Everything has this sort of "wall-of-sound" quality; big blocks of sustained chords that don't do much. That might sound fine when you have an actual group of real people playing the song because they can bring a degree of expression to even sustained notes through dynamics, accenting, vibrato, and all that other nice stuff, but your computer won't do that until you actually take the time to use your samples to create a performance.
Humanization is so important when it comes to the kind of music you're writing. You can't get away with this kind of thing when you write with a classical approach. It just sounds fake.
