Forgive this review I'm typing it as I'm watching it.
Part 1:
First movement: Good Tubas, woodwinds seem to be too loud at what I believe is the ephonium feature. Also see some spacing issues I believe. Good overall though.
side note: Your arranger did the same thing ours did for Canon in D by giving the trumpet part at the beginning to the clarinets and the horn part to the flutes.
Second movement: Lines pretty straight overall. Dirty trumpet run.
Part 2: Dirty trumpet feature.
Sorry this review isn't very good but it's what I got, apologies for any spelling mistakes.
