Heya Tol!
Thanks again for your comprehensive comments.
I'll see what I can do to address them.
I'm glad you enjoyed the percussion, since I put a lot of work into it, it's very deliberately sequenced. As for that clarinet part at 3:32, it's funny you should say it lacks dynamic change since the entire solo oscillates from one extreme to the other of the mod wheel's range, with it set to control volume and expression. On the other hand, I do agree that it's a bit hollow there all on its own, especially after the rest of the piece's fairly thick-textured sound.
As for that section at 1:59, you're right. I actually have the horns doing a very dramatic swell to flutter-tongue playing even, but I made a mistake with my mixing so they're not really apparent, I'll have to go back and fix that - thanks for pointing it out!
I can also boost those strings while I'm at it, though I deliberately had them fairly quiet so they wouldn't clash with the trumpet part soaring around over them...I'll try it again and see what I can do to balance them.
Again, I'm not sure I agree too much with you in terms of the dynamic range of the piece, considering the horns, the strings (especially the sul ponticello tremolo violin parts) and the bass clarinet, as I mentioned, all explore their full dynamic range throughout the piece. I think the problem is that you can't really tell because the percussion is dominant in the mix. I could turn it down, but it's basically the key to the feel I was going for, so I'm not sure what I can do to make the dynamic variety more evident.
Any thoughts on where you would have liked to see that little ending phrase go? I can definitely do things with it in other pieces, but I hadn't really considered it until you mentioned it just now, so let me know if you had specific ideas or if it was just a general "Hey, you should develop that more" kind of thing.
Anyhow, I hope that covers your comments, I'll go back and put in those edits I mentioned as per your suggestions.
Thanks very much for listening!
