Inventive!
This was really good mate, I liked the idea and how it was all put together, it shows your really thought about what you were going to do.
A couple of pointers though; the sound in one part was cracking and it sort of took away the mood of the piece, and also maybe include more sounds apart from the music, i.e. a whistle blowing or the sound of the pieces going into the board etc.
apart from that it was flawless, good job boyo ;)
