Well that is a good training to get used to Lights .
You can use the Lights that load with the Figure and set these balls up reducing the shadow on each to .5
and then important it is to add a Environment light or use the one that loads , Important is to add shadow to the
environment light else you will lose details . To make test renders use the Mat file that removes the Reflection on
the Floor that will speed up the render.
If you use a doll like in your scene Make a test render separately from the Environment hide the environment
using some spots and ball lights on the doll keep the distance of the lights so that it does not affect to much the
surroundings then Make the Environment back visible with its lights
sometimes it is also nice to make a fade effect for the background and front more clear this gives you a main actor in the image
not every angle needs to be lighten up
but still you doing a really good jop
ohh and one more thing sometimes you get better resuls to set the standard light correction from 2.2
to .8 or less in your render settings
