Very nicely put, Marcel...couldn't have said it better myself. Good job on the crop, too. I think your edit is a tad on the dark side, though.
To the OP: You have to be very careful with poses like that, when you're shooting from above the subject. Unless you're going for a full-body shot, that perspective is rarely flattering. Because your model is leaning back on her elbows, her entire right arm looks amputated at the shoulder.
