This is pretty dope

I love the vibe of this track. I would say in the beginning it feels a tiny bit out of time. This is especially when those ha ha's come in. So I would go through the vocals and make sure they are always in time.

Right off the bat, it sounds undermixed/mastered, like everything could be brought out more than they are.
The vocals definitely don't fit with some of the chords too, like at 0:27 for example, like ZUDDOX said.

One thing I definitely noticed too at 0:50 - the vibe and percussion is working really well with the vocals, but there's hardly any low end to back any of this up. I would add a sub bass, and a low pad to help give the track more energy.

Some things that are good though:
    - The gated synths are really nice, and I like the kick work.
    - The cymbals sound really nice, as well as the timpani rolls.
    - The piano at 3:09 is LOVELY. Would love to hear more of that!
    - Actually, all of the percussion is pretty awesome. I'm not huge on the snare samples you used, but that's just more personal preference than anything.

But yeah I would say the main things would be to mix and master this track to bring out the dynamics more, work on matching the vocal pitches with your chords underneath, and add some low end and low/mid.

Love all the elements at the beginning, and they come together nicely at 0:17. However, the bass is way too wide. Stereoization with bass is almost never a good idea, you can achieve a much harder and intense effect by keeping the bass mono and in the middle of the mix.

That being said though, the vibe of this track does go really hard. I like the pulsing lead accompanied with the percussion, and the samples throughout add good layering and variation. Really liked the "Panda" sample too, would've loved to hear more of that.

I would like to hear some more processing in the different elements such as more reverb, EQing, filters, etc., but like I said the vibe is perfect for what you're going for.
