The most positive thing about this is that the themes come across as being very bold. I don't get the sense that you are overly concerned with writing in a particular style or to please anyone's ears but your own. This is great, and I think it's something to lean into.
The pizzicato octaves in the violin part towards the end are not typical for the instrument and probably more difficult to pull off than what would be "worth it" for the resulting sound.
I would recommend that you continue listening to as much music, new and old, as you can, and infuse whatever stylistic elements you like into your own music. Overall, I think this is a great start, and I enjoyed listening to it.
