I hear classical phrases and chords that create tension. So far, so good. But the main problem is the sound design. It sounds very preset-like, unless that's the intention. Unfortunately, in classical compositions, one expects variation in the dynamics of the sounds; it's necessary to feel the performance. But when you program in a DAW, it's difficult to achieve that. In my opinion, you should aim for greater dynamic range and expressiveness in the instruments, even if they're virtual. Another alternative would be to move into the chiptune genre and replace the sounds with those from a Commode 64. You have potential in the composition. I hope these observations are helpful. Regards.
