I don't know if you know this, but I'm French. And English is not my strong point. So sometimes I have a hard time retranslating everything in my head.
So I'll try to be efficient if not subtle!
I think it's great! Really great.
First of all, I was taken aback by the 3/4, which works really well. The happy, carefree atmosphere. You can almost hear children laughing and playing in the water. There's a Joe Hisaichi feel to your composition (Studio Ghibli).
From a technical point of view, I'm in love with the flute melody at bar 20. It's splendid. And you've added a little ear-candy at bar 22 with this little delay on the melody, leaving a silence on the first beat. It's genius. And yet, your flute sound isn't really pretty (I don't know what sound bank you're using, but this flute is a bit screamy). And despite this average sound quality, you've managed to make a wonderful melody sound.
I was a bit long on the flute :)
As for the rest, the instruments respond very well to each other. There's room for all of them. The 3 sections flow naturally into one another (the 3rd, quieter section is a welcome way to complete the loop while keeping things interesting).
In short, good, very good, Nick!
(and of course, thanks for the score, I always take the time to read it on the 3rd listen to add to my understanding of your music)
