I like the way there is a reverse nipple up top. This is like a "ying yang" effect. I like the extreme closeup of the nipple though. there is a really intimate feel here, obviously ... its a bit too soft of focus though- glass cutting sharpness is best, especially with a chill in th eair :-)
Interesting exporation of light and shadow, but the texture on the breast is not very flattering. You can see the veins! The shot looks unintentionally blurry, but I do like the 'Yin Yang' composition.
