It sounded like a very superficial reading of this incredible sonata.
you hadn't really explored this sonata and delved into Mozart's dynamic indications and the reasons behind his choice of certain colors - subito forte, subito piano, pp to ff, etc
you started playing around with the tempo and it began to sound a bit flippant.
To me, the last movement was way too fast. It loses it's tragic nature at the speed you take it at.
