Something I'm hearing is that you don't really have a clear melodic line (which I tend to like). The synth you're using for the melody is kinda tough to really distinguish. Other than that though it's really nice and coming along well. I would try to to take the drums off the beat more as it could lead to some nice grooves. The mix is sounding great though.
Is the school system in your country similar to Chinese school system? I could never imagine being a teacher in a Chinese school, what's expected of students and teachers is just so different from what I'd be looking for as a teacher
