String quartet N 4 I/Part 2

Hi everyone. Here is the second part of the first movement of my fourth string quartet. Comments/Feedback are most welcome.

I enjoyed it very much. Very rich textures.

The time has yet to come for me to understand this kind of music. Despite this lack of understanding, I really like the piece (all movements).
The four instruments have nice independent parts, yet they form a dense atmosphere. I love the harmonies.
