Very busy music, nice job!
It's been a while since I left you a review, so I figured I'd drop by and leave my 2 cents! :)
There's a lot going on in here, which is nice to hear. You still need to watch out for clashing notes, though. One really noticeable example is at 0:58- 1:00, where you have the 7th of the scale (te) in the voilins, and the #7th (ti) of the scale in the french horn playing at the same time (which results in a minor second interval). This is VERY dissonant sounding, I'm pretty sure it's not what you want in this setting. I'd recommend modifying the voilin part to play ti instead of te, which will give it more push into the resolution at 1:00.
I'm pretty sure these dissonances are a result of sloppy editing. I know you've got a very good ear, so they probably weren't intentional. I think what happens is when you copy and paste parts, you push through and forget to make modifications to a copied part when it's needed. What I'd do is start isolating parts and play them together. For instance, mute ALL percussion, and start to play melodic parts together. If you play just the violins and french horn at 0:58 for example, I'm sure you'll hear that big dissonance, because nothing will be able to cover it up.
Keep it up Chuck, it's great to see you experimenting with different sounds and instrument combinations!
