Oh dear, Hard Coffee, here I come....
So... Back. Reviewing as I listen.
Study of LSD:
Intro sounds really messy and busy. Could divide the sounds a bit better. Here comes the percussion. Good levels and mixing there. The bass comes off as really weak, lacking weight. Background sounds or well... The whole soundscape actually, sounds really all over the place. You have some great ideas there, but it needs more work to express them more efficiently.
The random dialogue vox in the end part grabs the attention, forcing the other sounds together a bit more. Nice save, but unintentional, I think. Overall... Definitely needs more work, but it's getting there. Keep it up!
If I ruled the world:
This is... Incredibly off-key. The percussion is good, but everything melodical is a horrible earbleeder. I like the bass, though this high buzzer is kind of dry and annoying. The background FX is nice. More horrible cacophony.

And second drop. Again, the drops are weak. They just begin out of nowhere and statically progress further. Try adding some weighted impact to them.
Old man's Beefstep:
Atmospheric intro, a bit dry, but bold. Some hats... Nicely mixed. A pad... Could use some more reverb. The beat... Not too fond of the samples. The snare is kind of weak and lacks the punch.
The vox is good. Mid-bass is kind of overpowering. Overall, very strong atmosphere and soundscape, just not a very tight mix. Again, make things work together, not on their own. Nice flow on the second half, but the mix fell even more apart. Try some consistency in the sounds as well. The glitch sounds overused and completely random. Completely throws the listener off-track.
Uneaten Semitheatrical Reefa:
Straight to the point, huh. Strong bassline, but chaotic. All the layers sound apart from each other. I'd use that high synth as a background sound, it's too dominant right now. Break doesn't need much of a transition... But it's also really chaotic. I'd make it half-tempo in the beginning and then progress to full-tempo. Weak drop again. As with the others: great ideas... But too chaotic.
X-Ray Vision Invasion
Really muddy mix. Nice breakbeat, but the bass seems to drown everything else. The soundscape seems more solid, but everything gets completely overwhelmed by the bassline.
Keep it up, though. Some really nice ideas there.
