Really great soundtrack! Love the little tempo changes, the instrumentation is really good! Each track has well defined sections and concludes nicely. Its all very polished and complete.
It might be worth considering "breathing" with wind instruments, especially flutes/piccolo. Some lines sound more suited to a keyboard than a wind instrument. In a real orchestra they can stagger breathing if they have to but it's more idiomatic writing if you consider it beforehand. Also forces you to have good phrasing.
I think it's a good sign that's my only nitpick haha, well done!
