Strictly an amateurs eye and opinion but I believe regardless how beautiful the subject matter, the artist still has to have the talent to present it in the best possible way! It's not just a simple matter of point n shoot here's the picture... I think the model, the lighting, the pose and totality of presentation all work together beautifully here!
Let me just say that I agree with the comments about the beauty of the model and I am impressed with your photographic capture. However, this is what has me perplexed, are the adulations more for the beauty of the model or the beauty of the art. In a way I guess some might say the two are inseparable but I don't necessarily agree. Which would you prefer, to have your work appreciated for your artistic achievement or merely for its content? To me it doesn't matter in the larger scheme of things, but it does give one pause. Again, wonderful capture, just pointing out something that made me ponder.
