What Glenn Said, with the following additions and exceptions:
I very much like the first pose. The boy shorts, however, interrupt her lines. I assume that she had a limit of 'no bottomless' or similar, it's unfortunate because that interruption of lines makes a huge difference. Speaking of interruption of lines, I'd like to have seen her near shoulder pulled back a bit. That would greatly enhance the two most important physique lines in this pose: The line from the front delt head, down the pec and over the top of the breast, and the line up her back from her waist at her lower lat insertion to her rear delt, with her elbow bent ever so slightly so that the tip of her thumb would be about even with where her wrist is now.
In the second image, she's just plain ol' purty, and you captured that very well.
You stated that your goal was "no post processing" and you['ve done a great job, however, both images would do much better with a little "cleanup" sharpening.
In spite of the above nits (which are, to be sure, very much personal preference), VERY well done!
