This is a remix/arrangement/whatever of Ultimate Truth (Youmu's stage in PCB), done completely from scratch in FL Studio. I've never done anything like this before and have basically zero knowledge of music theory, so go easy on me.
Not bad considering that you are just starting with music in general, overall. Now for the rest:
Copying Bio here with the quiet build-up.
Instrumentation is too simple, making repetition an issue. Change around instruments at times in the melody and completely for the counter-harmony.
Also, more importantly the mix is too simple - it seems like a part of something, rather than something that can act stand-alone.
I find that the instruments have too much delay/sustain, and the release too short. Also I'd add a tiny bit of reverb to melody and drumkit.
I don't really have much like for the analog kit.
