I love this, Its such a subtle pose in a way, but the way you've drawn and exaggerated her curves just makes the whole thing cry out in a fun sultriness that just can only be expressed by the word "BA-BOOM".
I absolutely adore this gal ; I love everything about it. Her big hair is perfect (wish I could pull something like that off), and even though her waist is tiny, it highlights everything else about her, such as her beautiful curves. I love the subtle hints of brown throughout (esp. her eyes) and the way her dress flows down over her hips (which made for a wonderful reference). Her expression is priceless, and I love how you threw in the hint modern sexiness by adding in that little opening above her cleavage there . Words cannot express how much I love this.
For a second I wondered where her pupils were. I'm an idiot. XD
