Not that I am really qualified to judge these, because i surely can't recreate them.... but in my opinion.
In both, the out of focus areas of her body are slightly distracting to me. As well as her poses. She look a little uncomfortable. The first, laying on her arm as she is, looks to "posed", not a natural position for someone trying to look relaxed and seductive. The second, her arms look like she is trying really hard to do something with them but doesn't know what to do.
From my limited knowledge, the lighting look great aside from the white pillows, but she looks to be lit perfectly. The composition looks spot on. The color is spot on.
