Reminds me of Rammstein, of all things.

People with a classical music background, I'd guess, have a much stronger feel for dynamics and how to develop a piece of music structurally, and you are no exception. Great job! I like the way this piece moves and transitions.

My only criticism is that it ends too early, just as it's getting started! From the rhythmic vamping at the end, that's the time to really take it to the next level. Maybe use a fade to throw off the listener, but have it turn into a crazy rise, and then really go all-out with a big outro.

Nice job man, i'd try to add some more space and interesting transition sounds. You have the structure down but don't be afraid to pause every now and then to give your listeners a moment to think and collect themselves.
