I liked the arrangement on this one quite a bit, here. Personally, I really liked how it never really loses the more mellow atmosphere throughout (unlike the source and most remixes, which explode with energy after a short time). Even at the climax, even though it's bigger, it doesn't open up to a high energy atmosphere, and I thought that was neat.
One common note that only affects a small portion of your strings (the parts that hold the faster melodic portions): there's too much swell for each of the attacks. If there's a way to automate the attack so the strings don't swell into each attack that would help the realism of the strings greatly. For the slow string portions it's not a problem.
The drums were a little on the weak side. That could be solved with a simple increase in volume, though - just be careful not to mess up any production in the process, if you do try to fix it.
I liked this otherwise, though. Nice work.
