Not that I disagree on the point of NOT having more childlike races, but I don't think we have a lot of, 'Cute Short,' races in the game as is. Lalafell (Depending on your definition of, 'Cute') and Female Au Ra. Out of the 12 possible race-gender options, only 3 fit into that category.
Like I've said before, I'll welcome tall beastly female Viera amazons, and smaller, more refined looking males. An opposite of the Au Ra, basically.
