For some of them posted, Paul for tension I might have put the bottom square tip on the middle triangle like you have on the top. Might have created more tension? For order I might have made the bottom black square the same size??
For Roman's playful, I thought it could also represent order as the squares all seem to go up in size. (didn't notice the star effect at all :)) The tension one I thought was a good example as your eye goes exactly to the spot where it is different.
Al's does not fall into any category mentioned:) Perhaps playfull confused.........:D
Like David's bold, very dramatic. Could maybe fall under increase too?? Thought David's order could also be playful. Think it was order from disarray tried to be shown??
Denise very good example for order. No other category for that one to my eyes:)
James first post struck me as order, maybe a little tight as Fabs mentioned. The second one I found bold.
David's one for playful looks like fun and a caterpillar to me:)
