Good job, and nice choice of repertoire. You get the mood, and the change in the middle section, across well.
Of course this is a tough piece, with lots of hidden difficulties lying in wait (eg the pesky acciaccaturas). I get the impression you're finding it quite tiring, and I'd like to make a suggestion regarding the octaves (my observation comes with reservations, because I'm certainly not a teacher). It seems to me that your right hand moves around more than it needs to, thus increasing fatigue and stress. In particular, in the Db major scales, the movement in and out of the keys from black to white and vice versa appears larger than necessary. Possibly your fingers also could remain nearer the keyboard throughout the process (less vertical hand movement). It's of course hard to judge from a youtube video, but I think your octaves need a little more economy of movement, and that would have knock-on benefits re fatigue.
