Good luck to you too m8.

The story should go the way it goes. It might take 20 words or 2000. What if it would be more than 700 words it won't win the prize? Who cares?

Yes, it does usually disqualify you from the prize if you go over the limit. I've been writing in the 'finish the story' on and off for 2 years, and sometimes I've gone well over the word limit because the inspiration has taken me and time hasn't been a factor, other times I stick to the word limit and look on the comp as an exercise in editing.

Thanks for the constructive criticism.
