Wow this one is surprisingly Nice :D
But melody aside, the intro is bit harsh on the ear, I suggest using some reeverb. It's also quite long in my opinion, shortening it and getting to the "drop" part faster would be nice :)
You should also consider compressing the song to make all the sound stand out more and making it a bit louder. A easy and fast fix would be to just slam a soudgoodizer on the master ;)
All in all, you have the melody down, you just need to get the technical part dawn too.
