Ok, there! I found them!

I agree with Mikey about the beginning. It's not special enough. I would play the last note shorter. And a bigger cresc. Maybe it's the recording, but I can't hear any cresc.
So a bigger crescendo in the first two times. But then he doesn't write a crescendo the third time, just an accent. So I wouldn't do a cresc, but almost a dim. Then the f becomes more surprising. It's like a fire the first two times, the third time you think it will go away, but then the explosion comes.
The next theme was fine. Though, there is no legato slurs and a mark about lifting the pedal in bar 26, and I think that's cool if you do a small hole there. Nothing big ofc, but not legato. The same thing in bar 106-107. Take some more time from the g# to the c# and with a hole between them.
You have to practise more on the slow theme. The (I don't know the english word but) bars between the theme are way to concrete for my taste. I don't know what it, but it doesn't feel right. If I find out what it is, I'll tell you! Maybe it's the tone... I see it as French horns.. But that probably wont help you...
It really turns me off, and I actually stop listen when the notes are that.. not the same time. He was fully capable of writing gliss if he wanted, but he didn't. It's like a fantasy world in the woods, a la Narnia, and the centaurs are greeting you to their world. You're playing it as, I'm sorry, 3 of them are perfectly fine, but the 4th is a bit drunk and are always behind. It's only the first time, but it's the first time every time the theme comes.
And play with more bass-notes! It brings such depth to the chords, but I can't hear it at all.. And I know most people say that you should play the top note the most, then the rest way way less, but now I miss the nice little changes he makes in the middle.
then it's basically the same...
bar 441, where the left hand comes in, here the chords Has to come at the same time, and you have to grow 10000 times more than you do. Much fuller and bigger tone, I think it's the lack of the deep bass notes... And don't restart the cresc! Keep going all the way out.
The stretto has to be way more dramatic and desperate. And the same with the coda. The crescendos have to be more sudden... Everything has to be more than you do.
The last note has to take more time. It's from very very high, to very very low. It's just not something that is done in a sec...
I agree with pp about the standing up and stuff. For me, when I see someone do it, I feel like as if he had done a bad performance, and has to do big movements to make it look more difficult.
And let go of the piano when you're done. It was ok if Arrau held onto the piano in his last concert, since he probably would fall apart if he didn't. But you are fully capable of standing by yourself. And walk out a bit more proud, would you? It looks like you are extremely disappointed with what you've done. Don't look down on the floor and try not to wave your arms that much when you walk out.
Anyway, good job!
