Urgh... sorry to say that but I completely don't like this.
Chronologically, first part:
- weak kick
- rather static, not interesting lead sound
- strange melody
- weak buildup

<1st break>
- bad, cheap piano sound
- too many primes in melody while using piano
- effects don't match each other

<drop>
- harsh kick+bass
- just sounds bad

<then just the same>

Imho, starting with any big room is not a good idea because it's mostly technical. Making music is about making... good melodies and harmony, it's about getting proper sounds for the arrangement. For me, big room is quite an aberration - it usually lacks harmony, melodies are simple, yet sometimes powerful. Usually are based on 1 chord. For me, that's not quite what music is all about.
Why did I say it about starting with big room? Because if you somehow (don't know how) manage to get good at big room, you won't be probably good at any other genre. That doesn't work like that the other way.

I wish u luck, mate, but I was honest on this - this one is just bad.
