Hey Radii,
Nice stuff! I agree a vocal would go well over this. I like the lead and the progression in the 2nd drop. My feedback would be, I found the fx treatment (mix of reverb and delay) on the leads seemed to cloud their crispness in the drop, that is, the tails got in the way of the next note. Likewise, the FX / ear candy stabs seemed to be competing for space with the lead, maybe adjusting the gain, or using a chorus/small small reverb might help push them back in the mix a bit.
Keep it up man
