Here are two versions of the same pose. You can do that when you're using photographs. I like the tighter, top version but it's more "artistic" to like the looser, bottom version.
I have to remember when I'm drawing these photo-models that they are real live people somewhere, who offered their bodies to the camera so that artists they will never know can draw them. Those toes and oddly posed hands and eyebrows belong to someone real who lives with them every day. I am thankful for the models' service but they will never know.
