It's classical in nature, but not quite just in terms of the chord structure.
You seem to be in a rush to add new ways to make the progression pop, harmonically and technique-based (like adding new counter melodies or timbral interpretations). I know it's technically normal but it really stands out in this composition for me. I'm not sure why. Maybe it's due to the somewhat sectional nature of the piece? It also happens with the harmonic progression; it's fairly looking for new ways to advance when I don't think it always has to.
It is still a nice movement, but a little too sectional and horizontally focused, perhaps.
Good job!
