Fresh from the sketchbook; it's Catherine and Katrina ( Cat and Kat). I was just following wherever my pencil went and this piece is one of the results. Only details I know is that they're sisters. Cat, the elder sister on the left, may or may have amputated a leg and loves to tinker/invent with machinery and chemistry. Her mechanical aptitude is what puts food on the table. Kat on the right is the younger sister and she always wears an over-shirt their father used to wear and she's in charge of the home from cooking to cleaning to organization. The father is...absent? Away on assignment? Something that takes him away on many travels.
