Evil Threesome!
The intro definitely sounds evil, and evil DnB is not something I hear a lot, personally. I think it's fresh and awesome - I'm not sure if it's being overused anywhere else, but it sounds new to my ears.
That main background synth is maybe a little too loud, it clouds everything else. I'm not saying it clouds it too far, unless it's intentional it may be something you want to look at in the future. Pretty much all the focus goes on that instrument.
Now the bells come in, now you've got two clouding instruments. It sounds good, and definitely more evil than before, rhythm is still going strong and I'm digging the breakbeat you've thrown in halfway here.
So, now comes the next part I imagine... The intro is maybe a little too long, it may push some people into fast forwarding (you never want that to happen XD) or quit altogether, which you definitely don't want.
Anyway, more evil strings and evil setup, it seems pretty consistant and that's awesome. Now we're up to some nintendo-esque subbass in the background, which has it's charm! That 'sighing' sound in the background is a nice touch. The only problem I have here is that this part is getting a bit repetitive, but people who are already captivated shouldn't care. But it may be something, again, you may want to keep an eye out in the future. :)
I suppose this is the main buildup, sounds pretty full and, again, evil. :p Sudden stop and switch now, didn't see this coming... Bass is cool, seems more of a classic feel. Bells add to this feeling of nostalgia. Nice slowbeat you've got here, I've always liked that. Some distorted (?) choirs, while they sound odd and out of place, somehow they fit the theme. XD Don't know how you managed that, cool stuff here.
Further buildup and breakdown at the end, not much more I can say. Aside from the sudden stop, you could've done a little better there. <3
All in all, I like this track. It's like you said, three songs rolled into one but they still seem to be consistent. Good job!
8/10, 5/5.
