Harder better faster higher

Try different poses or angles. Sit on a table one leg hanging down, one on a chair or something. Reveal less. Wear a white shirt, and if you want you can have it opened down to your stomach, let it lay loose over your back but tight around your elbows. Research on poses you want to do before the camera is on. There is Google if all else fails. Don't look for poses, look for other features that makes a picture alluring. When I look at posed pictured, I not only look at the pose but also at how well the background matches to the subject who has been photographed, the lighting, the angle, the other objects that in the surrounding space that support to make the subject more prominent, the look in the models eyes, face and body, the emotions they purvey and how realistic or mysterious, etc it all is. You are really professional, and your face is exquisite and unique. I like your skinny. You just use everything you got, and make up what you haven't. Good luck~
