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!
