I agree with kazmord--it's so sad to hear that you had limited time! I would have loved to see what else you could come up with. The opening is effortlessly cinematic, so simple and yet extremely effective. A slow, intimate dirge, with scratchy, resonant strings, suddenly switching to a grand, sweeping horn line with a decisive timpani... and then a delightful, explorative pizzicato? It sounds really incredible. The leaping, hope-filled pizzicati chords are really great. Lots of creative ideas here, and I would have loved to see where you could take them with more time.
In terms of feedback, I would suggest adding stronger melodic components: while I love the dirge-like repetition, and honestly think repetition can be used very effectively (like you've done here), adding a melody might add a greater sense of flow to the piece. All of the shifts are a bit abrupt, and having a dramatic crescendo up to the final loud section would have given it that final push into greatness. Still, this is excellent work, well done, and keep writing!
