In picking images to post, a model must be BRUTAL! You cannot just pick images YOU like, you must pick images photographers will like. What do photographers look for in a models portfolio? Images that clearly show the model.
Thus those landscape orientation images in which you are a tiny portion of the image
are more images that the photographer should post iin his/her portfolio showing off his composition skills. The images you should post are the images that clearly show YOU, your figure, and your face. A photographer is not going to hire a landscape, he's going to hire YOU!
Just my opinion.
