It's a neat concept, but needs some development. Why just a single petal? In this case, the small bit of what I assume to be stem is distracting. Also, you could have been better served if you used a reflector to provide the tiniest bit of definition to the back of the hand/fingers. You mention the light being too harsh on the wrist, but rather than trying to "even it out," which would make the entire image pretty bland, why not use it to better highlight the petal (or better yet and entire flower)?
