Welcome Jan to our group and I hope you gain from this experience. I like the model and location. My suggestions have to do with the focal length and exposure. I'm think you had a normal to wide lens in this shot and due to the model slanting to the camera the head seems to be too large for the rest of the body and the breasts are at an un-natural angle. I think most of the photographers reading this right now would suggest 105mm (in 35mm format) or longer. This shot would be fine for a fashion magazine but does not flatter the model.
The other minor detail would be to tone down the hot spot on her chest and a little unsharp mask.
Nice portfolio of models and I think you are a dog and horse lover.
