Post a recording or a video. If you can really play 10/12 at a high standard, then the G minor Ballade should be within your reach, although it is a long piece and you must expect that it will take longer than a 3 minute etude. Four months isn't very long. I learned op. 10/12 back in the year 2000, when I was 12. It wasn't until 13 years later that I made a recording I'm happy with. No pupil in my studio would be studying the works of Chopin after only two years. Perhaps, if they insisted on playing Chopin, I would give them one or two of the easier preludes or waltzes. But op. 10/12 is pretty hardcore. Famous pianists like Yefim Bronfman use it for an encore!
