Meal Size Prototype

I'm doing design work for upcoming features on Plantry's roadmap. One such feature is Meal Size, to allow users to set a default serving size for their cooked meals.

In this concept it's illustrated by silhouettes of people to exemplify how many people the chosen servings might feed.

Do you feel it's an appropriate way of illustrating the settings? Would you be offended if you pick 4 servings, and the illustration doesn't match your family situation?
