Great song! I liked the main melody quite a bit. Also, really liked the beat at 0:26, very crisp percussion. Kinda wished you would re-introduce that pattern some time later in the song, but of course 4-on-the-floor is more dancey, strictly speaking.
The section at 1:28 reminded me a bit of Dimrain's style, pretty cool melodic elaboration on the chord progression you had going.
Great buildup at 3:22, particularly liked the pitch-rise thing. Mixed feelings about the fact that it then immediately drops down to a piano interlude. The interlude itself is good. I might have considered structuring the order of the sections differently, but it's a matter of taste, really.
What I really liked was the counterpoint melody that you introduced on top of the main melody. Different synth, similar enough rhythmically to blend well together with the main melody, and different enough rhythmically to be an interesting addition to the overall composition. The intervals between the two melodies harmonize really well, and it's just really nice to hear a level of melodic complexity in today's electronic music. Well done.
