The general direction you took is quite beautiful, but I feel there are some points to improve on. The general arrangements sound quite good and conveys that adventures feeling very well. But specially in the first song there is a lot going on that kind of distracts from the original intent. My guess would be to stay with fewer ideas and then let them count more like one perfect brush stroke instead of multiple small ones. The little flourishes, like with the flute, needs their own praise, since they added a very nice liveliness and playfulness to the orchestra. Don’t really know much about MuseScore and it workflow but there might be some points that could make the orchestra even more lively. First thing would be to look for more expressive and more fitting articulations other then shorts and longs the other thing would be to do with the dynamics withing the mixer of MuseScore since the flutes seem to get distorted with higher velocity.
Overall (and although the critic might sound a bit negative), this was quite a pleasant listen. Yes, like mentioned earlier there might be points to improve on but still the direction and general intention was already executed well. The only other gripe I might have would be the correlation to the theme.
