Sorry for the slow response, Feisty! Busy times.

I like the eerie bell-like synths at the beginning. The glitchy vocals at :06 also work well, and I like the sense of build into :38. The pacing is a bit slow, and the texture is a bit minimal at first. The blissful lead synth line at :39 could use a boost in the mix - the distorted vocals and acid synth overwhelm it a bit. Speaking of the mix, the drums are also a bit weak at times and could use some more compression and maybe even looser EQ'ing. There's also a lot of harmonic dissonance in the texture. A little bit of dissonance is fine when the piece is supposed to sound creepy, but once the vocals come back in at :51 it's a bit much IMO.

The rhythmic content here is good throughout. I really like the gritty riff at 1:13. Some of the transitions are a bit abrupt - there's not much of an overarching sense of direction to the piece, but rather a bunch of short-lived riffs that come and go suddenly. The filtering work sounds really good, like at 4:01-4:05 for example. It would be cool if you used that as a basis for more of your transitions.

You also do a good job of keeping the piece well-balanced frequency wise. For example, the bass-y breakdown at 3:12 still has these nice, prominent hi-hats to keep it from being too bottom-heavy. Otherwise, a lot of the piece sounds a bit choppy. You've squeezed a lot of different riffs and synth patterns in here, but most of the variety is created by adding and subtracting instruments rather than creating a sense of evolution from the riffs you start with. It might be good for you to consolidate some of your ideas and focus on doing more with those few ideas. For example, the vocal riff at :06 could have a different rhythm or pace later in the piece, or the synth pattern at :39 could use slightly different pitches, or even be transposed up or down an octave. Instead, right now all of these riffs sound very copy-and-pasted whenever they appear in the piece.

Still, I think the sound design, atmosphere, and rhythmic content of the piece are really neat. Most of my complaints are about the arrangement and mixing details. Keep at it, man! ^_^
