Really nice work, very heartwarming, and some nice sounds being used!
Watch the release of the oboe patch at the end of the melody phrases, its a bit sudden and jarring considering everything is so legato and smooth and pretty!
I would also experiment with notes in the duet section, there is some clashing between the two duet parts and also clashing with the chords, so just play around until you find notes that work both together, and with the chords!
Bravo!
