1 question:

Can you still tweak the cutoff/resonance of the main synth?
if you can, try to build it up, from low, to how for example, makes it less 'all the same'

and when you have done that, its a simpel but nice intro not?
then perhaps you should go for a PAD as for in the breakdown[a real nice when with maybe an awsome melody]
and then you could ad the best beat you can think of with JUST a bass

[for example, check out the intro of my new remix of Rank 1, the bass after 1 min of listening]

5 + 8 for now :)

Maybe towards the middle

Make everything start getting high pitched and fast for a few seconds, then a moment of silence and a really frenzied, excited piece?

Hm..

It sounds like it's building up to something when it starts, but nothing really happens, so I think you should have a lead instrument kick in somewhere. Use something such as a violin or a piano to play a lead melody, and then pan the lead you've got now to the sides and use it more as backing rather than the focus of the song. Also, maybe some sort of bell-like instrument every now and then to compliment the long held notes of the violin/whatever you choose, and the short chopped notes of the synth you have already.

That's what I'd do, anyway. Good luck.
