Lighting portrait study

Here's a quick and fun lighting portrait study based on one of Mathieu Maurel's exercice.
The goal was to reproduce the lighting of the reference shot, here Toy Story 4 and Souls by Pixar, with as few lights as possible.
I spent around 10 to 15 minutes on each lighting.

Here's a link to Mathieu Maurel's exemple of this exercise :
