Wow! This track has a lot going for it, and it hits most of the marks, though I do still have some criticisms I'd like to offer.
On the good side first: I love the panning. It makes it feel open and full, and it breathes a sense of danger as every instrument from all sides attack with a strong urgency that suggests the "running out of time" theme the track has going on for it. Compositionally, for the most part, it's complex and filled with little details to make everything not sound monotonous. The general dynamics of the song is balanced well, offering quieter parts to prepare listeners for the loud parts, and giving them that much more of an impact.
As for the not so good side, the song starts abruptly. The ticking clock is nice, however it can confuse listeners as a lot happens already in a short period of time in the intro. Speaking of which, it kinda doesn't feel like the intro goes anywhere if that makes sense. It changes a lot, but these changes don't signify any direction, or with any sort of cohesion. It really only picks up after the solo piano part, and then everything makes more sense. The instruments, although I'm sure they were the only ones you had, don't mesh together well. They work, but it doesn't offer anything spectacular, and the sharp high piano mixed with the sharp booming brass and the sharp woodwinds just overpowers, but not in a good way. Perhaps a little more mixing could have helped, although unsure this would necessarily work best for your needs.
All those aside, this track is still great and well deserving of its 4.5 out of 5. Great job!!
