In my opinion, this is a lovely piece!
The orchestration is quite nice and so are the melodies, countermelodies and harmonies.
Unfortunately, you did not include a saxophone.
The music reminds me of Tchaikovsky's Overture 1812 and his latest symphonies. The music sounds very romantic.
The beginning is beautiful as it is now, so please don't change anything musically!
By the way, the timpani sound font is amazing!
Well done!
