The stereo effects were incredible. I was listening on my laptop speakers, but it sounded like the echo on some of the sounds was coming from way out to the right of me.
At 1:13 I thought it was going to get bigger than it did. The slight tempo shift (?) with the triplets over top was sorta interesting but too subtle a change to do the trick.
In general I think it could use more rhythmic variety. Don't just repeat 8th and quarter notes, ya know?
I didn't notice anything at 1:45 or about the drums at the end.
Endings are probably the hardest thing to do right in music. Either you have to "ease on down" or "take off". But you shouldn't just "peter out" which is what this song did.
I think you have some really cool sounds going, and a lot of good stuff to build on. Add a melody. Add some rhythmic variety. Work on the ending.
