Are sticked to a crop factor John ?
If the model is looking at our right, we could think that more space/room should be in that direction.
However, the slight twist / rotation to the image makes it to have a dynamic sensation which pleases the viewer.
All this depends of the monitor I know, but perhaps a bit more contrast could be interesting mainly in other areas but the face itself.
But, looking at your site - the one you point at left - one can see that you have a coherent way to treat your photographs and this one just falls into that trend.
So, it is well done. The portrait for the day !
