That noise riser pretty loud and high pitched, it actually hurt my ears when using headphones. Also that synth starting at 0:15 is quite bare, and doesn't fit with rest of the instruments that well. And, eh, Fl-keys just don't make it :P
But the other instruments were pretty good, especially the supersaw (though you ant go wrong with supersaws).
And i assume that Masterlizer's mastering works, because it sounded pretty great.
Melodies are quite catchy, but really typical for house / edm. At first I could've sworn that i had heard the exact same melody before. Also there were some parts where the melodies sounded a bit off-key, especially at 2:41 and 3:00 - 3:33.
What can I say, It's pretty basic house stuff. But it lacks certain creativity and the unique twist that would turn this song into a "Wow!"- able, or so to say.
