Question about the Furnishing Design contest

Hi! I'd like a clarification, if possible on a part of the Furnishing Design contest. The rules state that one of the requirements is:

- Size comparison by person

Do you want me to illustrate the different angles of the furnishing alongside a silhouette of a generic human figure, or should I illustrate all of the races - like what the item would look like alongside a Roe/Hyur/Lala ?

I'm sure that a size comparison to just one of any of the races would be enough, as long as it's clear which race it is.
