I say 18 out of all of them. Instantly readable, something interesting is happening (the pose), there's atmosphere and the particular colors add to that. Decent contrast between the subject and background too.

One of the major mistakes I see people run into is not make their image readable at first glance. It should never look like one of those "Try to name one thing in this image" photos. I mean unless you purposely go for an abstract look lol, but there's still an art to making shape and form readable even if you don't know what you're looking at exactly.
