I liked your sextet. I think I remember it to some extent from when it was posted before. I don't remember a whole lot so I can't compare the two versions.
You might want to tell people in your post that this is 3 movements and 6:30 minutes long - I'm not sure if the reason it stayed up so long without comment was that people weren't sure what they were getting into and so didn't have the patience to listen all the way through, but it is a possibility. As for me, I did like it a lot better the second run through.
