Well... I think this is a conceptual music competition, not a classical writing competition, so the use of instrumentation or "ear candy" as you put it is important in providing some of that atmosphere. Orchestration and arrangement are pretty fundamental parts of 'educated' classical music, after all.
Sorry, I'm not trying to bash James' piece, it's just a bit annoying having spent so many hours arranging and mixing to be told that it's essentially just cheap tricks..
