Thanks MFC. I think you're right about the background. I wanted the photo to have an overwhelming sense of blackness, but the arms are too small and loses definition. I'll try again after the challenge with a tighter crop.
Dan, I think this is really a good idea and well done. (*)I'd probably compare results using a little less background...I'm guessing you would have the same effect, but be able to appreciate the arms a little better. MFC
