This has such a calming and beautiful feel to it, I really enjoyed it. The music develops nicely through the different sections, and it’s easy to just get carried along :)

Very nice tune! I like how the Flute pairs with the Brass.

The other comments pretty much cover everything I can think of so beyond that all I can say is that; the wind melody is very pretty, and I like the backing piano and constant arp movement, and I really liked that 7/8 sounding groove at 2:18 -- overall a splendid and charming little track, I like how light-hearted and whimsical it is, well done! 

opening piano riff is fantastic, almost works as a motif itself. wind melodies definitely are a bit continuous/busy - I'd consider leaning into the style you used for that opening section some more, I think that piano part is actually quite memorable, especially with the sparser countermelody on the wind. also, maybe the final section with the bouncy piano could be augmented by something like some spiccato bass/cello or even percussion?

The melody is great, and all the different versions as the track gets more lively change the feel of it nicely!

One thing about the melodies I'd suggest looking a little more at is the phrasing, since in both melodies there is really no pauses which makes them feel a bit like really long sentences, and since both of them are played on wind instruments there is really no spots for the players to breathe.

But still, the melody is really nice, good work!
