nice use of the old vocoder.
the guitar could do with some reverb.
as could the drums and bass (not too much just enough to bring them together).
and the drums should really kick off in the last section (mind your clipping here)
your vocals sound as if they have clipped and the whole mix seems to clip up at the end.
try the default mastering suit and have a little tweak to flatten out the levels towards the end.
