The first pluck (not the chord stab) sounds kind of bland by itself. The synths seem to overlap too much to me, and they fight with each other for dominance. The melodies by themselves sound okay, there are a few awkward transitions. At 1:50, a rising low pass to fade in treble from low to high would have made the following part more effective, it could could be combined with the increasing volume. I think there were some weird volume imbalances throughout the song. The volume might be okay, I'm not using the best speaker.
