You really should hire a professional photographer! #1
I am guilty! That is not an image that I shot but I am guilty of showing up to photo shoots with no concept or direction for the day.
Planning on winging (improvising) is no plan at all. But planning something like the above photo is ludicrous! Having lighting and space is not enough it also takes skill and ability to compose a great image.
Though I wing-it from time to time the finish product is always the same at-least 10 awesome images. But as I move forward in my career planning has become a necessity. It makes the day move faster and it keeps the model happy.
