Needs variety
A nice effort at the Dimrain47 sound. I'll admit he has some tough-to-imitate stuff. Here some constructive criticism:
I know the arpeggios were unique but even then they could use some work. Be creative, go for whatever your head comes up and tweak it to make it sound better. The key change at the beginning is very dissonant and doesn't sound very pleasant. It makes the piano sound out of place. Try sticking to the same key at the beginning. The beat and the bass in the background are repetitive to the point where it's annoying. In general, this can make the listener lose interest fast (I speak from my own experience in creating techno). Try to change the chord progressions and mix up the beat. Altogether just play around with different stuff you can think of.
