Hey, I'd have to agree with what most people are saying here. It certainly lacks sub, which means when the chorus/drop hits, it lacks a bit of umph.
That being said the rest is great, that arp at the beginning is sweet and there is a cowbell type percussion running through which I like.

Overall, you've definitely done the track justice and i'm a huge Porter Robinson fan! Just work on the sub to give it a bigger impact.
