I am trying to improve my German at the moment, my level is somewhere between B1 and B2. I studied it at the University some time ago, and my level was B2-C1 at the time, but I didn't use it for a long time, so my German skills worsened.
We may practise German together, if you want. It seems that your level is higher than mine, though, so perhaps for you it won't be that interesting. But we can try, what do you think? Message me if you are interested.
