For the studio portraiture I think my favourite outcomes are the coloured lighting ones, they have a fun feel to them and I like the way all the detail on the face stands out.

Here they are in a virtual gallery.

These photos will look nice together because they both share a common shade of blue, and also have a contrasting red and green next to each other. The high amount of detail on the skin in the photos I think looks really visually effective and high quality.
