College class work White balance / portraits

Two weeks ago our class work involved looking at The Guardian's personal portraits selection, and taking images that could be used by the Guardian. Below photos of Lynn,Roger, Dave and Darren.
Images were slightly cropped.

Couple of weeks ago we were taking photos with different selections of white balance on our cameras, along with learning of white balance adjustment and the effect it ha got on the images.
Taken with Nikon D3000, standard lens 18-55mm, ISO 100, F5.6, S1/8
