That was, indeed, very beautiful playing. For me, it's a little on the fast side. I know all editions give this 50=dotted quarter note, but very few observe it literally. Take Pollini, for example, who I think really carries it off splendidly. The basis for his interpretation is 50, more or less, but he plays with the tempo, in that, he follows the intention of the melodic line. When there's filligree work he brings out the direction of the line, and consequently the 50 tempo slows down. Then, he's back to his basic tempo. Many play it really slow and it's quite frustrating to listen to. Your basic tempo is very good and musical. But don't follow it literally. For example in the cadenza like section of the final, listen to what you're playing in the r.h. and slow down a bit, accordingly.
I really enjoyed hearing it!
