I agree with b0b3rt

Especially at 0:11 the main melody sounds very unclear, as if the tempo suddenly changes. Also, maybe it's a good idea to sidechain the hi-hat that hits every 2 steps, to emphasize the kicks more. Nice melody and synths though, nice subtle variations in the melody. Then again at 0:52 an unclear part which kinda ruins the flow, such a shame. At 1:41 the mood of the song changes, so maybe it's a good idea to add a little effect / sweep. Then again, you said you're going to change that. Maybe add a sub-bass to the dubstep part? I find it's lacking energy, but maybe that's also because there isn't really a buildup to it.

Nice little demo though, looking forward to the full track.

Peaceful

It's harmonic and peaceful. It's nice.
However I feel it's a little empty at 2:03.
Instruments sounded very clear and the song was perfectly mastered.
It's really beautiful. The more you listen to it the better it gets. Totally perfect for some sort of ending scene in a movie. Good job. =D

Very good!

It certainly doesn't lack variation! The main point with this track is that is doesn't have a catchy melody. I also don't really like the higher synth at 0:41, it's a cool idea, but I think the melody is a bit random. I like how you mixed very on-beat melodies (or however it's called) with a bit swingy ones, like at 01:12 and 01:46. Also the buildups are very great. Finally, the ending is a bit random.
It's a 9.5, not a 10 because of the lack of a catchy melody.
