I'll fix the chain in the R4R thread by reviewing this :).
I think what Chainsawninja is trying to say below is that you shouldn't add the bass in the buildup. at least not at it's most powerful. Try having a weaker bass and weaker kick drum play during the buildup then have the bass and kick at it's most powerful when the drop hits.
I'm not that good with Hardwell stuff though so I'm probably not the best to explain it, but I would advice to listen to some other trap or hardwell-ish tracks and see how they did the drop. At first, try to copy exactly what they did then when you understand the mechanics of it make it your own.
Anyway it's pretty nice for a trap beat it's smooth and pretty cool and chill.
It got dynamics in different part of the songs which makes it awesome to listen too even though it's repeative like a trap beat should.
Here's 4 stars for you :).
