Based on the artist's post, that is if there is a lot of photos of their work the word count can be lower for sure. It's the 1 photo posts for say a photo contest that just don't qualify as "quality". There have been some drawing posts for example that have few words, but 12 steps of their drawing that I'm more then happy to see come in.
Hope that helps clarify a little.
Yes, it does. Thanks.
I hadn't noticed the rule change for this week, I've just posted my entry. I'll edit my comment above to include it.
