Well done, I loved the three track. I gave you some suggestion if you don't mind. :) Take care!
Chapter one: Well done, I really love the synthwave vibe. I can see these colors and idea in front of my eyes. What I can suggest you a little bit, if you would like to give a more old vibe, you can give a little bit pitch shifting with an LFO on some instruments. It will be sound a little bit dirty, that gives more depth for the instrument. But well done. High five for the slow flow.
Chapter two: Oh God I love so much the sub like drone sounds. Hell yeah, It sounds like a dark movie. I love the unison trick. The glitchy thing drives me crazy, hell yeah. I really love the arrangement. My ears a little bit pleased for more bass, more like sub bass.
chapter three: Just suggesting, a little more reverb for the drops. Cool lead sounds, nope, cool synth sound for all of these. I like how you keep the mood of the track. well done. Only a little bit more bass. :D but it's my taste.
