I love this. It's a gorgeous, well-orchestrated, unique piece, which is something that's hard to create in a musical world that is (imo, anyway) possibly a bit over-saturated with the genre as of late. When the horns entered and brought the song to life at 0:31, there was nothing I could do EXCEPT press a 5-star rating. Absolutely stellar tone quality and attention to detail in the brass, and the whole sections involving the choir never struggled with it to fit it into the "aural spectrum". As for the rest of the instruments, they are astonishingly well-written as well. The piano solo between the two orchestral sections was notably fantastic. The sudden change of pace and color that it provided was perfect.
I see what you mean by not having the time to finish it in the way you would have liked (or at least, I'm guessing). When the climax rolls around, the swell doesn't really amount to a whole lot. It feels like the spirit of the piece is renewed, but it leaves just about as soon as it comes, and doesn't really give you a chance to sink into it. However, it's still very powerful as it is and only further serves to show how much talent you have as a composer.
