The wonderful Catherine in a photographer’s mainstay b&w portrait. 
I quite like the b&w version (compared to the colour version on the right), I find it a strange mix of high key of the face an low(ish) key of the top. Not sure if the skin-tones really work (could be a bit too high) and I’m not convinced of the crop which has a more powerful feeling to it than the original (in my opinion) but the more plain, obvious crop has a more classic look to it.
