Music Composers Unite!
It's cute that you called it fish in c I think you meant to allude to sea. Very Nice music,
Pleasant piece. No criticism. Very good use made of the thematic material - one might almost say efficient - which makes you an ef-Fish-in-C expert! (Sorry...ok, there's a plaice for everything...not here!)
It's moving between the lyrical and sprightly simplicity makes it easy to listen to; enjoy.
(I did notice your unconventional placing of the Oboe above the Flute in the score and assume that was intentional.)
