It's so awesome.
The crescendo is excellent.
You've mastered the art of counterpoint with the oboe run during the first part opposite the piccolo doubled by the glockenspiel. It's very, very well composed.
And that descent at 23" (end of the second measure of theme B) does something to me, I can't quite put my finger on it, but I love it. My ear expects something more conventional, but you launch into the second part of theme B in a brilliant and surprising way that I really like.
I'll stop there because I could go on describing everything that works so well.
