Been playing with this chord progression for a while, finally got around to getting it down in the DAW. Completely unmastered, so you might have to turn up the volume some.
I actually fucking love this. It remind's me alot of my own remix, but with a more moombah-ish, big house-ish feel rather than my own dutch house.
My advice? Her vocal's are a tad bit muffled, like the lower frequency is more prudent then the high, you should add an equalizer, and bring the hi-shelf up about maybe 2.5 decibel's, and maybe add a very small amount of reverb, give's it more of that "studio" feel.
As for the drop, Add another saw tooth and and raise it maybe on or two octave's higher and make the semitone for it a little different (That's how Archie and Avicii get that 'Big House' Sound) And maybe make it side chained a little bit
But Seriously good. Good Jerb.
You Probably aren't interested but here's my own remix - It's dutch House

You might want to get a compressor on the bass-line to get it to punch more. It sounds kinda sloppy. I'd actually make it a tad bit quieter, since it seems to be competing a bit too much with the kick.
Nonsense also made a good point. The vocals have a bit too much low frequency. I wouldn't say they're muddy, but they do kinda lack prominence in the higher frequencies, which is where all the interesting stuff in voice happens.
