I will go ahead and say that using the 7 Deadly Sins will be fine as long as you attach some form of demon to the story, don't use the Sins themselves as a plot point.

Also, I am going to say no on it being a poem. Largely because it would very difficult to judge a poem against a short story, as they would both require different judgement techniques, and I want to keep this fair and impartial across the board.

So, yes to the Sins, no to the poem.
