I ahve to say that I agree wtih Matthew.. the one MAJOR flaw is that it's TOO SHORT!!
It's so lovely.
And it has a surprising "happiness" about it.
It almost gives one the impression of what we would get were we to put Mahler, Berg, and Richard Strauss into a giant blender and grow a whole new composer out of that (rather repulsive, when you think about it) mixture!
