It's a mix.
Funny.....the 'hard' part is terrific (as much as I listened to -- didn't go through the whole thing); the 'easy' part, IMO, needs a lot lot lot of work.
Actually maybe not a lot of work

but a different point of view (I guess I ought to say "IMO," because of course one could say it's just an opinion -- but I'll bet you).
Before I say more about that, I ought to compliment you more on the "fuoco." People who haven't worked on it (or who haven't heard people fall on their faces with it) might not realize what you're accomplishing, but it's amazing.
Fantastic. Fantastic.
I mean, it can use a little work too (could use some dampening of the hair-raising, some of the rushing) -- but it's real good --
exciting -- and extremely impressive.
But the opening: There's no sense of flowing, no sense of long line, in fact I have to say no sense of line at all.
The reason I say that maybe it wouldn't take "a lot of work" is that it seems you're currently "hearing" the opening just how you're playing it, which is in little punched fragments.
Do you really like it that way?
Much of the problem, but not all, is that you're playing most of the 'easy' part way too loud. But besides that, it seems you're thinking of it mainly in 2-note groups rather than longer ones, and the problem is magnified by the occasional breaks of 'space,' which really really interrupt things.
C'mon -- make it peaceful, and flowing, and beautiful!!
You've got the hard part.
Now just get the easy part.
