First, complete admiration. These two pictures show how much goes into a great photograph. The model's physique is a work of art, as are the poses, expressions and makeup. The camera work is also high art - attention is seen in lighting, depth of field, color saturation, pose and composition. The costume and accessories are also high art.
Second, observation. The left photo is pure sexy. The girlishness of the figure, bust and hairstyle are bespoke youth, then there are cues of allure - my eyes are drawn up past the spread legs, along the curvy thigh, past the thrown back shoulders, and right to the sloe eyes. Mission accomplished.
The right photo has the same components, and a wholly different effect. The model still looks to the viewer, but the cues are gone. Her pose is relaxed. My gaze circles back to the... plushie? I'm a dude. She's obviously a hot dame. Why does she make me want to play with an ugly toy? Such is the female power.
Now for the negative. Aww, the suit is wrinkled. It must be really hard in real life to replicate the impossible comic/manga standard - clothing like so much paint*, while even Latex and Spandex cannot really match the movement of human flesh. Yet, as I said in my other post, this is awesome.
* or diaphanous beyond any fabric (not to mention breasts that defy gravity and faces that are preternaturally infantile, check out my ecchi fave folder for those)
