We've got a nice pensive intro. Nothing is offensive to the ear. I think the only part this piece neglects is production elements. The wow factor. But not to worry, that's not that it sounds bad at all. :)
I really like the way you've written your chords, and the structure is nice and comprehensible. There's not an overabundance of elements that aren't adding to the track. Everything has its place. This is good. I would however pare down slightly the reverb tail on any instruments with sustains and percussion.
I'm not really liking the strings -- they have that key string slow attack. You can drag them ahead of the beat a bit to get that gross feeling of almost a full sixteenth beat waiting for them to come in to go away. Experiment with that.
Your low harp, I would edit the velocity of these notes. You may even make two instances of the harp and to get that traveling effect, pan some ranges of the harp to the left or right as you see fit. Panning of various instruments I would experiment with more, more than anything, as your chord writing is pretty good.
Your percussion writing is good. I would bring it up in the mix a couple dB. Also, experiment with different panning. It sounds very centered here. The ending of the perc is the only part that particularly left me wanting more. You could try throwing in a raked cymbal stinger on the end at 2:14 to tie things off. I would humanize the velocities of your cymbal hits here as well.
I feel like we're locked into the same BPM here in a piece that wants to move and flow. Maybe experimenting with the BPM per bar can give you an edge here.
Volume wise, I feel the strings especially by 2:00 are a little too loud in the mid range for the melody and the drums should be pushing through more.
But otherwise you've got a solid piece. Writing wise I'm very excited to see what else you have to bring to the table, and I applaud you for making MuseScore sound good in any case. Great work!
Thanks for coming out to NGUAC!
