No idea how old you are - but if you want to make any progress, you need INSTRUCTION. This lacks and form or development - same old same old over and over. Many instances of poor voice leading - and not demonstrated in any way that sounds intentional (as perhaps an indication of the protagonaist's mental state?) You need more education in instrumentation ( the capacities and best/worst application of every instrument) and then orchestration - how to best distribute your musical ideas ( of which there were very few original ones) through out the orchestral forces. Most of the instrumental parts are dead cold boring to play - except for the rapid pizz passage of violas - and that better be DIVISI, not double-stop pizz!
So we all here applaud your ambition and intention - but none of this is ready for public consumption, or submission to any kind of students competition - yet. You need a far more extensive an thorough education is all the areas of music - starting with better theory skills. You need to listen with a SCORE to many works of composers you admire. Bad I also suggest that you devote yourself to *absolute* composition for a while - no program or story, but a far better grasp of your mechanics. Prove to yourself ( and us . .) that you can write a decent minuet, sonata, etc. - or something with really good voice-leading - or something that best exploits a woodwind quintet or string quartet - before you write for 100 people, 90 of which will be bored stupid playing half a dozen notes. enroll in a good class, where your work can be shared and compared with others. Having ONE TEACHER may not be what you need - perhaps that are happy that such a your person *wishes* to do this - but if you are studying, well - I do not think they are teaching you much. Good luck - hope to hear back form you in maybe 6 months, minimum.
