Super-quickly, realising time, etc etc.
In scene I, the horns look like they're an octave too low. Also, to look more "legit", you might consider having the horn part without a key signature. If it's quick to fix, you could sort out the crotchet (aka quarter-note) rests in the brass parts.
OK ... scene II

Ditto horns, rests in scene II

Scene III - main "issue" to address might be horns throughout (the total work). Here, it's in a good register, but a long way beneath the trumpet. Therefore possibly 8ve.
Bar 21: stet. (Not listening at this stage, only giving the scores a once-over.)
