I really only have one complaint. The backgrounds at 2:25-ish to 2:57 really don't line up to the speech. The speaker (by the way, who is it? What speech?) is building up to a point, and talking about a particularly dark subject at that, but the music remains relatively static right before the drop. After the drop is pretty good, though, as is before the speaker comes in. As far as that goes, I agree with Endayne -- you put the vocals in at exactly the right moment.
(Actually, after going back and listening to it, the music remains static into the drop. Consider adding something like a sweep or something. I don't know. Bring out the drama of the speech.)
