They are both very similar and beautiful. A difficult choice, for sure! There's something about "A" that makes her look mature, sensuous, and ready for the (SL) world. "B" appears more innocent and young, yet bold and daring. It may be the nose ring that makes me feel that way about her, hehe!
In the end, this has to be your choice. But if I had to pick one, "A" would be my choice for you. Good luck with your decision! 😃
