VIDEO: Scriabin Sonata No. 2 Op. 19 Mvmt 2 - advice please! :)

Hello people!
I'm looking for some feedback on my playing of this piece. It's a bit scary to upload, since it is very difficult to play, very easy to hear if you do any mistakes since it consists of a lot of "clean" harmonies washed in pedal (one finger slip will be heard the entire measure...), and since I'm far from finished with it yet.
When I decided to learn this around the beginning of the autumn last year I started practising it the wrong way, and used some pretty dumb fingering in places as well. When I finally, after months of slowly learning it, discovered that I couldn't play it fast without getting tired the first minute, I realized I had to re-learn it from scratch. I did a lot of thinking about what my teachers taught me about technique and how I could get myself to relax. The difficult thing for me is that there is a certain point where I feel that each individual note needs to be played so fast that it is impossible to listen to each one of them and use my eyes to see to it that they are correct; I have to rely on that my mechanical memory is 200% sure of what it's doing and will do all the work for me (I'm not quite there yet though - so I keep practising it slowly), so I can concentrate on relaxing and keeping the wrist flexible.
Now I can at least play this "decently" fast several times in a row without getting tired. I did play a bit faster than I'm used to in the video though (I seem to be playing it around 4:15 normally), I was stressed about having a mic recording me, so my technique suffered a bit from that. The scary thing is that to be performance ready it should probably go even faster  

Anyway, any kind of feedback on my playing and/or technical advice is much welcome!
