Couple of other points.
Picture 9 : Your face in this picture is so perfect!! The rest of the image is a little cluttered in this instance, but the fingers on your cheek, the angle of your jaw, the texture of your complexion, your eyes, that look, and the hair. It is beautiful. A really lovely portrait picture.
Ok, now a little test. Look at picture 20, then flip back to picture 19. Did the image become more sexy, or less sexy? Let’s do that again. (Imagine I’m the optician, better this way, or better that way? Actually my optician is German. Sometimes she turns my eyelids inside out. ”If you want pain” she once said joking, laying on the accent, ”I can give you pain!”)
Well anyway, I do like 19. Not sure if it were deliberate, but the vertical boot breaks the ‘all one outfit’ look and makes the blue triangle between your legs look like an accidental exposure. A small point (no pun intended) but it works. The left thigh is gloriously smooth and shiny, and angle of the boot makes it look like you are wearing a pair of trainers. This triggers another image: a tree-lined, grass-verged street in the summertime, and you almost skipping along looking really fit and healthy in a pair of trainers and a white cotton T-shirt. You haven't put your jeans on this morning, because you feel like going out in shiny blue latex stockings and a shiny blue panties instead. That mental image makes you look inappropriately and outrageously exposed, feels intense, and adds extra intensity to this picture too. Picture 20 does not have this.
