Nice shot! It doesn't capture some of what I think is the best of Weston's sense of form, though there is more to his work (I love it when he captures a subject with notable depth that is conspicuously flattened thus abstracted with his capture -- I think your subject was too flat to start with to recreate that). With that in mind, I think the contrast, lighting, framing, and spirit of your shot are spot on. I really like it.
