A few months back after watching the Halo 3 Believe Ad, I decided to compose my own version of the song. Then I went even farther. I made my own custom diorama (on a much smaller scale though), and took a few pictures. Compiled those pictures with the clips in the original ad and with my own music and walah!
Enjoy!
