Alright so you seem to noticed the intro was lacking. I'm not going to tell you how to fix it because I think you know what you want it to sound like and that's perfect. Even if you wanted it to sound just like you completed it. I mean I liked the sample used for the intro. In fact I like your overall use of the sample and the drum following along, but then I start to get lost with the heavier sound. I feel like it works for a bit but gets a little heavy. Then towards the end of the first half before the silent moment the sample is over powered and I feel like it falls off the tracks just a little bit.

The track continues after the momentary silence and I like the second half's start up, but I think it builds up too quickly or possibly the heavier sound over powers the track again.

So conclusion, I love the sample and how you used it. I enjoyed the drums very much. Hell the drums and vocal sample go well together.
I'm not a fan of the intro nor the overpowering sound of what I think is orchestral instruments. I could be wrong on what it is, but its too much.

Don't take this wrong or even let it discourage you. I am simply one listener and you are a great mind. Keep up your work and press on!
