Looks to tall to be a Little girl. :P
ah well.
She's not that tall. It's not like a tiny little girl, but she's definitely not teen/adult. Tween tops. I had a 10-year-old in mind when I drew her. O.o
It's funny the way they portray 152 cm in anime. I'm that height, but in anime, people that height look even more like children than I do. That might be it.
