Not bad; I enjoyed this if I'm being honest with you.
But now, I'm going to answer your five questions in the description:
Is it any good? - Yes, it's good enough to listen to, and it's good enough to be a backdrop (besides the words in it).
What do you not like? - Well, there's not much I don't like, but I'll tell you that the bits in 1:21-1:26, 2:48-2:53, and 4:15-4:20 are very empty compared to the rest of the song, and the transitions to them AND away from them are unexpected, and you want a smooth transition from one bit to another, but in this case, it's not a big deal, like at all; I'm sure people can deal with it.
What do you like? - I like that it is early hip-hop, I like the slap bass, I like how you add rock elements into it, I just like how you structured this track.
What should I focus on in future projects to make them better? - I think you should work on your transitions, smooth transitions make your tracks better. And put a bit of ear candy in it for extra flavor.
What can you hear that I obviously can? (I need perspective) - I can hear the theremin, I can hear the backup guitars, I can hear the power chord guitars, and I can hear those little vocal shots, too! There's more I can hear, but let's not worry.
Overall, I'm giving five stars aside from the little transitions. Nice job! :)
