Well the pictures are nice and clear, so we know that you can use a camera. Pretty girl, Nice cars. If you are really serious about getting into this style of shooting... it is going to be up to you to focus more on the big picture. The upskirt shots are impressive, but I do not know who would publish them, plus they can damage your name as a professional. Grab a posing book to better direct the model, and also think more about the overall purpose of the image.
If that is one of your first shoots with a model... I suggest you pursue this because these shots are not bad at all.
