Zena is drawn in Derwent Drawing Pencils on Canson Mi-Teintes paper. 

Zena is the daughter of a friend. I could never recognise her, which is embarrassing, and I thought if I drew her portrait it would help. When I took the reference photos she was getting over mumps and her face was still rounder than normal, but I had to grab the moment as she was off to university in a few days.
