There's a little distortion on those bells in the beginning, feels like, and synth cello is almost grating on the ears, but what it lacks in real instrumentation here, it makes up with good composition and mixing. I could do with a little more velocity and modulation on the bass, and perhaps a more realistic amp. You could even change up the bassline to eliminate those straight 8th. Those are what make it sound so synthy. The portamento is great though!
Sounds great! Keep up the good work!
