Review time!
Not Finished: Obviously not finished, but regardless, please watch those keys! Nitro and Zero aren't in the same one. I'm still training my ear for this stuff, but it sounds like they're just one semitone off from each other. There are some nice ideas for intermixing the two themes here, though.
Sins of Our Fathers: I was hoping you'd repeat your round 3 style, now that I don't have to feel upstaged about it! Yeah, this screams MGS. Maybe a little bit too much so--not just the style but in some places the exact same transitions are used as in the main themes of MGS3. Sounds just a tad less polished than your last entry--a little more mechanical, a little weaker sound quality, one or two off-key chords, ending cuts out slightly abruptly. But these are minor nitpicks on an overall amazing piece. I do have one major concern: I can't pick out Concrete Man. The three Zero themes are plain, but I've listened to this piece about 10 times now, and Concrete Man several times to refresh my memory as to how it goes, and I can't find it.
Breathless: Country music and nasal congestion is a bad combination. As you say, it's a little fuzzy and hard to pick out the lyrics. Compression would help, but enunciation could be better, too. Otherwise, it's a simple and elegant piece. Simple verse-chorus-bridge lyrical structure lends itself perfectly to this kind of compo.
My Choice: Not much to say about this one. Strader does what Strader does, no surprises here. I think your voice is actually better suited for the more growly sort of thing you did last time. Certainly no complaints about production or source usage, but the arrangement is a little vanilla.
Crystal Cipher: I absolutely love the justaposition of the high-reverb wood blocks and digi-tribal drums with the synth bass. Incredibly effective. You've come a long way since the simple synths in Serpent's Spiral, which I already loved for its arrangement, but your instrumental use is even more effective now. Anyway, this piece: Use of Stone Man is very light, or else overly interpreted. All I hear clearly is the opening. I do hear Metal Man very clearly, although briefly. Otherwise, I really love the arrangement, production, everything about it. This one is going into my long-term collection, no question.
Dread Zero March: Well, no one knows better than I do that orchestral is a tricky and time-consuming style to accomplish as a newbie remixer. I'm also not sold on that Dive Man percussion thing. Better luck next time.
Bubble Man Chip Chip Churray: What's a churray? A 15-minute mix is pretty ballsy; if it's not utterly stunning, or changes completely a couple of times (in which case it still shouldn't be one song), the listener is going to get pretty fatigued. I characterized this as meandering before the 4-minute mark. The dischordant notes and distracting panning don't help. Then in the end it just gets weird: 11:24 starts a section that sounds like a carnival, then at 11:48, a sitar? Too many ideas. Focus on one and make it kick ass. If you'd spent the time it took to arrange the 11 minutes you didn't need, you could have improved the production quality of the 4 you did, and it might have been pretty good.
Dividing by Zero: Sour notes, abrupt transitions. A-B-A arrangement with no interaction between the sources. Vanilla synths, not much in the way of arrangement. A few inspired moments, mostly at the beginning and end, but otherwise there's not much here of interest.
Transducer: Classic SuperiorX. Not a terribly exciting mix, despite some vertical layering. Does everything it's supposed to do--good production quality, good source integration, it just isn't much fun.
BGUNF: Synth hammered dulcimer and synth strings. Interesting; they're just real enough to be identifiable, but fake enough so that they don't sound like they're supposed to be real. A fun take on Zero-X3. Then the solo bass trying to singlehandledly, clumsily, tack Skull Man on to the end. Oh well.
You're Not My Real Dad: Nice, seamless transition between the two sources. Arrangement right in that sweet spot between copying the source directly and substantially rewriting it. Does everything it sets out to do. I'm getting a little fatigued with atmospheric pads in this compo, but that isn't the fault of any one person.
Wily Wars... The Punishment Due: MMX and electric guitar, the classic combination, and Solar Man is thrashtastic icing on top. This is an unusual combination of sounds, though: You have a beautiful, crisp voice (despite illness and vocoding) that doesn't mesh with those dirty guitars very well. Could we get the lyrics? The X1/X3 mashup is a little messy, especially in the ending, it gets a bit chaotic there. Otherwise this is an epic arrangement.
