Very nice and charming track, I love the main melody, which comes through really clear and sets a nice uplifting vibe.
I would have to agree with Eetu about the lack of variation; it could also be good to tweak the volume of the tuba/horn (whatever the deep brass is) to be a tad quieter and then bring the volume back up when the melody comes through-- this is just an idea of course.
Overall, very nice track! I like the anvil-hitting percussion in the back, and the use of only brass instruments is very cool to me, well done! :D
