I see that you're actually moving to an eastern asian design, and the fact is that Japanese animes and videogames often use orchestral music (with a bit of rock and electronic music to modernize the thing) as background music.
I have composed some neobaroque music under Free Art License inspired by the works of Nobuo Uematsu (Final Fantasy) and Toshihiko Sahashi (many animes) (
http://www.gnu.org/philosophy/license-list.html This is a free and copyleft license meant for artistic works. It permits commercial distribution, but any larger work including the copylefted work must be free. It's GPL-compatible.) available in MP3 192K and Ogg Vorbis Q7 format that you can use for OpenArena (here
