a short critique (and when I finished my original typing of this it was only 80 words out of 100 so I had to add this; but I think my critique is fair and reasoned regardless of the word count... what do you think?)--
Cons: the line between the background and the floor is really distracting and the fact that the subject/model is dead center is kinda boring.
Pros: Model has a great pose; Wonderful contrast between the neutral grey and the vibrant red of the coat. Great exposure.
Suggestions: Even if you like this composition (centered), perhaps you can "spice" it up by experimenting with changing the direction of the light-source, or perhaps the angle of the shot.
