The movements in the other thread (which could be deleted) are much changed, so I include all four movements here, in the right order, or, better to say, the order I finally settled on.

The first movement is a bit long for a .not file upload, but the other three movements are safely within limits.

I have shied away from trying a string quartet because I had not confidence that I could do anything with one. I haven't gained much more confidence, I'm afraid. It has been a real struggle. However, I am not entirely unpleased with what I hear.
