Find this a beautiful portrait and i like the pose and the toning. The only 'negative' that results from the pose (and you probably got some comments on that) is that it gives the nostrils (not exactly the most aesthetically pleasing feature) a lot of prominence. 8
Very attractive model; I'm not sure I want to look up her nose, though. Still, I think it's a fun and unique perspective, so it grabs my attention. Does this say "you?"
This is a wonderful shot of your nostrils, unfortunately, that's not really what I'd prefer looking at. everything is leading straight to the nose, so that is definately the main focal point of the shot. your focus and clarity are good, and the background works nicely for this. nothing distracting there. would have prefered a different angle though.
