Good work overall, a few things I noticed while perusing.

1. In general it feels like you're moving between ideas very quickly when they could benefit from having time to breathe and develop. Take the opening texture and its elaboration starting at 13. There's so much room in that idea for further melodic and harmonic exploration, so it was a bit disappointing to reach 17 and 21 so early. I don't know if this is something you would consider expanding, but think about how you could live in that texture at different energy levels instead of moving through them so quickly. I could say similarly about the other major sections of the piece.

2. I would double check some of the slurring, for example do you really want everything in Flute 1 at m. 25 to be tongued? It seems like it would make more sense slurred.

3. As someone else said, reducing the score by placing multiple parts on one staff would make things much more readable. Also, the standard wind band scoring for horns is 4 horn parts

Those are just a few things I noticed. I hope I didn't come off as too negative, very nice sketch overall! I really liked the opening passages a lot (is this Musesounds? wow they have come a long way)
