wow, brief aside here, i wasn't expecting to see anything written in Finale PrintMusic in the compo... that's where i got my start in 2003-04 with Finale PrintMusic 2002. even just seeing your score screenshot takes me back lol - cool!
anyway - very pretty, emotional piece you've got here. the harp/piano and especially the strings are really nice; sometimes i wish the arpeggiated parts deviated a little more, but i would find this very suitable background music for a game or cutscene. the mood is dark and wintry! it actually feels considerably less lighthearted than the artwork you chose for inspiration, where i maybe would've imagined some cute pizz plucks and glockenspiel for these cute fellas having a good time in the snow. but, with that said, i can still see what you had in mind, and it sorta feels like what i'd be feeling by zooming out to see the whole landscape, neighborhood, town around them on a snowy winter's day.
although the EWSO sample libraries help out, i know from experience it's pretty hard to get humanistic sound out of Finale without *a lot* of finagling - un-score-like finagling at that, where you're dropping dynamic and articulation markings all over the place and it looks unreadable or silly. but that's one aspect where i think this piece could really benefit; the arpeggios and other repeated rhythmic figures would feel less like a computer was playing them back if their volumes varied more, offbeats were de-emphasized, etc. basically what i'm saying here is the playback isn't doing your score justice lol, i see some good clean detail in the page you provided, so it'd be lovely to hear a real recording; real players would handle so much of that stuff themselves :')
