I like this one: you have identified it as "M" but it's not really.

Overall, I think you are having a good time, modeling, and that's important. Of all your photos, I like number 2 the best, but notice your left foot is turned, awkwardly. that's partly your lack of skills, and partly your photographer's lack of attention on making everything right in the image. The other one I like is number 18, which has a nice candid look, but isn't sharp, and the lighting was not at all controlled in the image.

I think you need better photographers, and you need to work on your own skills, as well, but otherwise, I see someone working at becoming a model, and not holding themselves back, like so many do. That is good, Try to find some more skilled photographers to work with, It will make a huge difference. Shoot for TFP, if necessary. That's what TFP does.........gets you in the door to work with better photogs.

I would also encourage a small weight loss. Maybe 5 lbs, as the camera adds about that much, do to the nature of optics. Compare your images to my page, and perhaps that will help you to see the issues.
