Congrats on winning the round MW. Pretty sweet mix for the most part.
Off the bat I think there is too much reverb on the horn call. If it's EWQLSO then I know you can't really get rid of all the reverb on the samples and it's probably stacking with the master reverb.
The harp is really really mechanical. I would take the plucks no more than four notes at a time and make sure that each one is humanized and varies appropriately in velocity. A little rubato here and there just to widen the downbeats. If you watch live orchestra players, especially the plucking ones, there is a really really long moment in preparation of a pluck on a downbeat. It's tough to explain but next time you see an orchestra watch the basses.
The bells are a little too piercing against the lush strings. Maybe filter off the highs or readjust the EQ. The fake vibrato kind of takes away alot of this mix's greatness especially around 3:13. I don't think this is EWQLSO.
Overall I really liked it, it reminds me of Star Ocean 2 in a good way, but some of the instruments don't seem to match each other.
The starting call sounds very very different from the rest of the mix and this becomes extremely apparent right around 3:13. After mixing different sections I always do a few long mixes where I just listen to it from start to finish and do some final tweeking as I listen. This helps with uniformity in the sound.
Great work for only a week's amount of time!
