Very cool idea! I especially liked that first "drop". My only problem I have with it is the pause at 1:23 seems a little too long. But other than that, I really dig it so far and I'm looking forward to the finished product!
The pause at 1:23 is more of a trance inspired element. A stylistic choice. It's not a bad one, it just could use some more flavor over that time to not make it feel like nothing is going on. Move more transients, make it a more gradual climb, etc.
Track is pretty good on a production level, well done! Is there anything specifically you were looking for feedback with?
