B&W High Key studio portraits
I like these, the lighting is good and love the expressions, well done.
I feel some of your cropping is too tight, try using some negative space on 1 or 2 images to add an element of fun (I re-processed one so you can see what I mean)
Regards chopping off people's head, I quite like it, but be bold, either do it as in the first couple of shots or leave more space above the head (referring to last 2 shots)
