Well I see you and DeAnne have done it again. Very nice. I'm somewhat of a beginner too and don't nearly have the opportunities to practice my craft as you do. Especially with such a willing and available model. You are lucky.
With that said here are some suggestions. I love the composition but I would have preferred the lighting to have more contrast in the style of Chiaroscuro lighting. You have some but I'd like to see more difference between the light and dark areas. See Chiaroscuro and Rembrandt Lighting
. This would really accentuate DeAnne's wonderful curves and valleys. I think it would do a lot for the B&W version.
Some purists might prefer not to have the jewelery but in my opinion it's a choice. I like the contrast of pearls on woman. The wedding and engagement ring says to me.... "Sorry guys she's taken" which you may not want for a commercial glamour shot but that may be the message you want to send.
As I said I'm definately not an expert though so I'm sure the more experienced here on GG will provide more insight.
Keep them coming. You are inspiration to me.
