Awesome work, and beautiful transitions, colorful and interesting rhythms. Truly sounds like something I'd have heard in an old Disney animated film on VHS.
I really like this piece 🙂
However, just a couple of things to point out to ya. Some places, your rhythm notation, while the playback will play it correctly, and it's also technically right in terms of the notes covering all the beats in the measure, lets look at Measure 8 for the harp's Treble Clef staff. The rhythm notation there should be:
( ♩ ♩ 𝄾 ♪_♩ ) instead of ( ♩ ♩ 𝄾 ♩. )
because of that eighth note rest. gotta finish beat 3 off with an 8th, then tie into beat 4 with the quarter note 🙂 It's much more legible that way for a player, and it's just simply proper. This same thing happens in a good few other places in the score, from what I'm seeing. Although, while you don't have to do it that way, it's considered the formal grammar for rhythm notation, and if this were to be performed, the instrumentalists would appreciate it more that way!
Also, the other thing I caught, was starting at b.32, with the violin solo there, ALL those accidentals!! You're still in the key of Db Major during that statement, except your notation reflects C# Major instead, hence the excessive amount of sharps and naturals seen there.
Based on the playback sound, I'd assume you're using MuseScore Studio 4.4.4? If you select all bars within the sections with those accidentals, click the "Tools" tab at the top, and select "Respell Pitches" it should automatically correct all of that for you, in case you hadn't ever used those utilities before.
But overall, my observations are just what I'd be sure to correct, if it were my score. I'm not an expert composer, just a musician with a knack for composition, who's untrained in the craft of doing so.
The piece sounds wonderful, and I think would be an awesome piece to be played live and recorded. Appears to be pretty fun for all parts involved, and has a nice, well rounded and imaginative vibe to it, that I think is fairly brilliant! Do some'ore stuff!
