I love the subtle synths that fill this piece. It's easy to make really loud noises, but it takes skill to make the listener pay attention to something quiet.
I searched for "frost temple" on google and found nothing, heh. it was reminding me of Ice Cavern from Ocarina of Time, but a google proved to me that that song sounds nothing like this one. So who knows that this is a remix of. :P
That aside, I really enjoyed this piece. I feel like you have real talent with dynamics. Everything in this piece sounds great and it all works together very well. I hope to hear lots of good stuff from you in the future. (And feel free to hit me back with a review if you get the chance.)
