its nice to finally see some medtner in here! hes really underrepresented here at pianostreet. you really seem to have a good grasp of the concept of the piece. however, your playing doesnt seem very confident in some areas, and it sounds a little choppy sometimes. however, that climax was very good, and you did play it "with desperation", as medtner notes.spend a little more time on it to iron out the kinks and to make your playing a bit more confident. and yeah, that piano just sounds horrible haha.
