you really need to read up on producing realistic orch sounds. There are heaps of articles on net.

Listening to this I couldn’t help but imagine what it would sound like if you ran the sequence through diff sounds that aren’t trying to emulate real instruments.
If you layered some nice ambiant sounds & apply some eq to the layers to give them some depth mmm

Work your drum sounds also, try layering a couple of hhats etc and eq one hi & one low.

Great work. Sounds good so far. : )

nice. also soundwise. does this use samples? doesn’t sound super realistic but very pleasant, no pure simulation it seems. rather highly original. very nice sound.

upload the MIDI files (in a ZIP) and I’ll see about drums.
