The thing with models is that they
are cateogrized. When a photographer hires a model they are hiring them on the basis that they're look is perfect for the particular story/mood the editorial is trying to project.. Obviously different editorials require different facial expressions/moods.. Snejana can't be smiling or whatever in ice queen / fierce editorials right

Snejana has perfected the cold diva stare and perhaps thats the type of stories/moods the photographer is going for. Fierce , cold and emotionless

At the end of the day the photographers/magazine crew picks the photos they feel are best suited for the direction the editorial is going for..
