Very cool track. Voted for you. Good luck!
Please check out these orchestral tracks:
I use Cubase 6 (64 bit) for all of my orchestral music. When composing more loop based electronic music, I sometimes prefer using Ableton Live. Using the 64 bit version of Cubase is great when you need a large number of sample libraries in your project.
