Woah, this is an inspired elaboration of a really simple source... I love Abe's Oddysey, and the minimalist ambient sounds accompanying the eerie gameworld. I very much like how you've brought out the melody and percussion, added an impressive array of instruments, and without departing far from the vibe of the original sounds (actually, I hear the slight departure as an excellent choice), have come out with something truly listenable.
At 3:20, the drum stutter sounded out of place to me. Apart from that, very solid sounding mix.
New-Australian... Works for me. =)
