Sisters? | Painter 6

I really do think theyre sisters. Quistis being 18 and Rikku 3 yrs younger, same hair style, same taste in clothing (orange...), showing their bellybuttons =P
The difference could be the height (doh), Quistis being mature and Rikku a very lively girl.....all that ^^;; can't think of anymore reasons =P
The background may be a little ..weird but I like it this way ^o^
