I really liked the beat, it was a nice balance that was chill, yet kept my attention. To be honest, I feel that the string/pad parts were the best. Absolute treat for the ears. I'd say work on the glitchy leads the most; I don't know how electronic works, but maybe it's as simple as you not having good enough VST's?
In short: Love the overall rhythm (And the great piano intro) favorite part was 3:17-3:47, my inexperienced EDM opinion would say maybe a slight increase in variety/changes within the drops!
