I had similar thoughts actually. The normal voters don't see the criteria and depending on what it is, someone can not follow it as strictly and make a much more eye appealing and attention grabbing shot than someone who follows it to a tee. e.g. like someone making a more dynamic shot when it said to do a pose.

But I'm hoping this will be balanced by the judges who do know the criteria and will score accordingly. Just make the judges scores of equal weight to however many people vote and it should be fine.
