Lovely! I'm not at a proper computer right now so I'll leave some overall impressions with my limited ability at the moment;
it's light where it needs to be, and lower when it needs to be... almost to the extreme. I don't want to call it clichéd, because it's not, but I think you can play with the audience's expectations more.
lead in to D had a couple strange notes in it. Same with the lead into G I think.
Instead of straight sixteenth/32nd notes in the high winds, perhaps use grace notes sometimes (not all the time) to drive energy a bit more but that's just personal taste.
I think starting the low section (F) monophonically instead of homophonically took away from the energy. Since the parallel section is in counterpoint, starting with homophony won't take away from it.
overall, fun piece, and good job!
