One little comment about this pic, everything is perfect in it. Most people looking at it would be amazed by it and have nothing bad to say... It's not exactly a bad thing, but with nude photography you want everything to look flawless, with her fingers barely showing below her arm, to me, it seems distracting. It's not a huge deal and not many people would even pay attention to it, but when you shoot nudes, make sure that everything is perfect...and double, triple check, then check again. Just some advice, but you are definately on the right track, great pic, lighting composition.
