Haha, awesome.
Pretty cool :D
There are lots of remixes of In the Hall of the Mountain King, this one's really good imo.
The orchestra hits are a good touch.
Every once in a while the drums kinda screw with your perspective and it sounds really cool, so good work.
(Also, A Night On Bald Mountain is a totally different song. Just sayin')
Work on the mixing a little and this will be a little better.
