I like the Black and white version better. In the color, her right rib seems too prominent because of the contrast in that area, and I feel it pulls away from the face. But in the black and white version, it doesn't compete as much with the shapes and contours of her face and arms. Good work
I do prefer the color version...but why is the ground under her right arm the only part that is grainy rough in texture?
I think it would look better like this as that texture catches my attention...but this is only my opinion of course. I softened that course texture and smoothed the skin a bit more.
