Hi littlewierdo,
you panned piccolo (I think it's piccolo) hard left, imho it attracts too much attention sitting there (maybe move a bit closer to the center?). And the other thing, about stereofield again, is that the instruments enter and leave in such a way that it creates "holes" in the sound picture. Well, maybe they don't leave entirely, just become quiet for some time. For example, between seconds 30 and 35 there are two brass instruments, can't identify them precisely, one is on the right (I guess it's tuba), and the other one is at something like 10-11 o'clock. It just doesn't feel right, maybe these 2 could be closer to each other spatially.
On the positive side, the piece is alright, does give an appropriate feel, judging by its name. Very appropriate use of percussion. And of course, you'll need to work on the dynamics, as you mentioned, so I wont't continue judging an unifinished product.
I'm using headphones, FYI.
