Hi Riaan,
I definitely like the second shot, you can really see her thinking, although I think the crop is a little too tight, but then again I could also argue it is not tight enough. I would have stepped back a bit to allow some working room around her for the first shot and then moved in close for a second more intimate composition.
The last little nit-pick might be to mention in image 1, that you have cropped her leg through the ankle joint. I was told by the old guy at the club I used to go to (who passed away a few weeks ago unfortunately), that you should never crop through a joint.
#2 is still a nice shot though, just a little too tight/loose on the crop for me, but I definitely like the way you work your B/W images.
