Funny you should mention that; the person who requested this piece said, "I like the Waltz of the MPP, I want you to make something like that."
Therefore, a bunch of similar instrument patches and a few days later, I had created this. I'm not a huge fan of creating something so stylistically similar to something I've already made (I think it's better for development as a composer to branch out as often as possible), but a request is a request, so voila.
No offense taken; I'm sure there are plenty of EQ issues. :P I plan on expanding this piece to 4+ minutes, and in that process I'll probably work more with the balancing.
Thanks for the review, I'll be sure to listen to some of your stuff. ;)
