I like the orchestral approach, you did well, but let me give you my two cents about what you can improve:
- In my opinion, the melody played by the plucks in the beginning does not seem to "go" a certain direction, it doesn't feel like it comes to a conclusion, or resolve;
- This one is optional, but I see you've used sounds from FLEX. While FLEX is a pretty good plugin, it is still a synthesizer, and because orchestral instruments are real acoustic instruments, they are going to sound better if you use sounds of the real instruments, recorded. Most samplers, especially orchestral, are quite expensive, but there are free options such as BBC SO Discover, which I like, and I use it pretty often.
I really enjoyed your music! Looking forward to seeing you in upcoming competitions!
