Thanks a ton for all the feedback!
I agree with all the notes here, especially the ones that pertain to the flutes. I did actually try playing these by hand, but I'll definitely try experimenting more with the velocity. The note about overlapping notes might actually work really well with this piece.
I did consider adding in another part in the first piece to occupy the lower frequencies, but couldn't put something together that 1) I was happy with; and 2) didn't clutter the mix. So I decided against it for this submission and hoped that the drums + center guitar part could fill that space, but I'll give it another go in the next jam.
I'll be sure to give your submission a peek later today to compare. Thank you for listening :)
