Though the mix was short, toilet goat had a really awesome idea going. The intro was very interesting and had some neat sounds (particularly liked those random shouts). Then a sweet guitar melody came in, which I've always thought would work wonders with this song. The synth that comes in a 0:23 had a REALLY awesome sound, and there was a cool build going on after that. My only gripe is that the song didn't continue after that synth melody, because there is a really cool melody in the source that follows. Mix quality wasn't too shabby either, though the rhythm guitar seems a bit shy in the mix.

The other 2 mixes had some pretty decent ideas, but they could really use some fleshing out. Some more instruments with some variation, more going on at once, etc. Though there's nothing wrong with simplicity, I feel like this source has a lot going on that could be put to use.

Toilet Goat - This is an interesting start. I wish you could have finished it. It's too short, buy you know that of course :P.
Xsquader - I like the samples you used. It's a little noisy, but I like the combination of samples.
Inrade - This is a really calm song, compared to Xsquader's song. The ending is too long. Still I liked the way you differ the source. For a first mix, this one is very good.

Inrade's is complete. Even though I like what Toilet Goat has better it lacks the completeness that Inrade's has and that puts Inrade's over Toilet Goat's for me.

I like inrades "breakbeating" stuff, and the lead sounds really nice, and it's not repetitive sounding.

Xsquader had a nice beginning but the lead didnt somehow fit, if a different lead would've been chosen it could sound better IMHO.

Toilet goat's is the most polished and has a pleasant atmosphere, but is a bit too undeveloped to take first.
Inrade had some nice arrangement ideas.
Xsquader's was a little bit harsh on the mastering. The rockin' atmosphere brought some clipping and heavy distortion which was a little bit painful to listen to.
