In terms of critique, the main lead could use a bit of eq, it overpowers the rest of the track. It would also be cool if there was a breakdown back to just the arpeggio thing at the start. Other then that amazing job.
I definitely like it! The places where you cut the bass for a moment are very well thought out. the melody was very pleasant to listen to.
Have you listened to any SizzleBird? He makes some really good chillstep.
My only critique is that you might want to add another instrument voice some how. Sizzlebird has some awesome violin playing in many of his songs, which gives him uniqueness and makes his music more memorable in the context of the vast amount of electric music out there.
