For Euphoric Consequences, The use of , I don't know, chords? Feels a bit repetitive. Anything to mix is it up would be great, maybe a slowed down chord/progression. Or that thing where you play a less harmonic note and build around it in a pattern that is not a chord. But overall the compostion is great. I also feel the piece would fit a soothing a background music and thus should be mildly quieter.
If you want to make your orchestral music super popular give every individual a time to shine. As opposed to everyone playing at once. But you could just do that in another piece.
None of the orchestral music seemed to stand out at all, There is no climax! Possibly due to the flute playing the entire time? I don't know.
This isn't a military lock step music where you follow the beat judiciously.
An orchestra is supposed to REALLY stand out when they play music! Your video doesn't. I don't know if that's because of the limitations of MP4 vs a real orchestra or what.
I failed listening to music in college.
