These were shot from a very close distance, which is causing a slight bit of distortion of the size of her hand and body features. She's a very lovely woman, so she's an excellent photographic subject. I like the first picture better, since the background is better controlled. When a subject has her face pointed away from the camera but directs her eyes back toward the camera at an extreme angle like this, that is known as "eye cut", and is almost universally (cross culturally in most cultures around the world) perceived as conveying sexual interest, so that makes these shots "sexy".
I wish the background in the second photo were cleaner...the stuff in the lower left corner area and the angle kind of dillute the impact of the second shot.
