Good song. Nice and simple.

Overall It's beautiful, although I have to suggest some things:
1- When the "Drop" starts, turn up the volume.
2- '' '' '' , make the beat more powerful, not too much, just a bit.
3- '' '' '' , put some bass here, just to make a soft base.
This suggestions are personal preference, but I think it would be cooler.
Anyways, nice work. ;)

Ohohoh .. It's very exciting!
