Sweet.
The melody in this is cool, especially with the piano dancing around with the synth. And I was diggning how the piano faded out into that other bouncy synth.
The fading was awesome, so I don't have a problem or anything. You kept movement in the melodies, everything flowed nicely..
The piano, once again, was GREAT.
I'd have to say that was a very productive 30 minutes.
But if you wanted me to throw in some constructive criticism then here:
Honestly, what you were doing with the opening synth, which led later on in the beginning, was fine. It had a lot of movement. Me personally, halfway into the song, I would have thrown the piano in and thrown in some nice chords to flow with it. Honestly, I don't have much to say. I wish you'd make it longer. lol
