Hey man. Thanks for your patience! Finally have a relatively free evening.
I like the creepy pads at the beginning - there's something ghostly about them. Some of the other instruments sound a little out-of-place, though, like the bass guitar that first comes in at :19. The part at :43 was a bit dissonant for my tastes, and had a lot of murky low-pitched tones that didn't mesh too well together. The rest of the piece feels a bit disjointed, with a lot of sudden transitions and isolated ideas for riffs that don't really feel like they're leading anywhere. I like the crackly atmosphere and effects at around 2:20, minimal though they are, and the rhythmic content during some of the busier sections of the piece was cool too.
Again, I'm going to suggest that you think more comprehensively about the chords you're using at a given time, and make sure that all of the notes sound good with all of the other notes. It might help to write the chord/melodic progression in a single instrument first before you assign different aspects of it to different instruments. And remember that a little repetition across different sections of the song is a good thing; right now, this piece almost feels like several separate songs played in a row, which is a bit jarring.
When you feel like you've incorporated my advice, feel free to PM me again. Cheers! :)
