@McDroneFace , I looked at the C piccolo part for Charge of the Uhlans for concert band. It appears by accident you posted the PDF twice as they are both identical.
I am not a flute player although I have a flute. Looking it over, the arpeggiated triplet passages may seem busy but I didn't notice anything that would be considered technically difficult, but I could be wrong. I am mainly a clarinetist and saxist.
It is a quick march at T = 125. A Washington DC street march in the cold of Winter might be around 120. British marches were a touch slower, around 108. It appears to be a happy march, maybe something a circus would have their high flying trapeze artists or clowns on unicycles in the center ring.
I am not sure what exactly are your concerns, part doesn't look any different than other piccolo parts I have seen, but again I could be wrong.
Could you further clarify what you are seeking help on? It may help some in this forum with whom the flute is a natural for them.
And, by the way, welcome to the forum!
