The problem I see with #1 is something I have been advocating for quite some time with female subjects. Do NOT have them sit flat on their bottom! A better position IMO is to have them sit on their hip, barring that, place a small pillow underneath one of their cheeks. This will eliminate a horizontal waistline, naturally raise one knee higher than the other, slenderize the thighs and help accentuate the essence of the female form...... the ess curve.
Also IMO, the forward rolled shoulders give the impression of meekness. I feel any type of boudoir shots should show the subject has power, confidence and is comfortable in their own skin. Chin up and chest out, so to speak.
Pretty girl. Thanks for sharing.
BTW, I work from home..... youporn dot com is SFW with me, just have to log off the URA first. Not that I do, just sayin' hehehehe
