Though I have not done glamour photography or studio photography I did take ' life drawing ' (which is drawing nudes) so I have some ideas on this subject.

First, I want to say that the human body by itself is a work of art. So if one just simply photographs it, it's no more art than if one photographed a van gogh painting in a museum. What has to happen for the photo to be art itself, is that the beauty of the work of art, like a model, is brought out by the artist (photographer) and they are able to show us why they think its so wonderful.

You went about this the right way.. you had an idea (dream) that you strived to bring to the image. You used everything you could to do it. Lighting was your main tool and the lighting on the first image, highlights the right places and cast shadows in the right places. for instance..the light and shadow play on the shirt that shes wearing make it just cling to her body. The soft frontal lighting brings the back of her figure into silhouette which leaves some to the imagination. The light on her chest is just beautiful.

But is it a glamour shot? Well yes and no. The thing I like about it that makes it different than glamour shots or playboy for that fact is that the subject is beautiful but approachable. What makes her approachable? The wrinkled backdrop. In glamour shots, everything is perfect and they give a "look from a distance" feeling. When I was a teenager, my brother told me that he just loved the look of a beautiful girl driving a junky car. I never forgot that. It also doesnt have the obvious look of someone trying to be sexy. She looks wholesome. However, the pussycat look on her face is a little too submissive looking which, teamed up with the posing of the hand does push it a bit toward the glamour look. I do think the one hand is a little too suggestive and the other one is unnatural looking. No one stands with their right hand there.The place where you cut off the legs... perfect in my view. Just think of the famous portraits like the one of Isabella Rossellini for a look of substance in the face. That pushes it past glamour.

The second shot is of course beautiful. But truthfully... been done and been done. It's still beautiful but the first is more unusual.
What else do I think it needs to stand out as a beautiful work of art? one word.. Impact. More unconventional lighting. Yes, I know I said your lighting was good. it is! But it can be more dramatic to really make the shot stand out.

Your composition is creative and beautiful but if you want it to really be art, place her hands in some way to seem natural and not sexy, go past the rules in lighting. Past what looks great and into what looks amazing and different. And lets us know what kind of person she is just by looking at her face. Let her expression show a woman of substance. Where we can see her beauty inside and out.
