Here we have Rosalina heading to the pool on her cosmic observatory.
There are a lot of illustrations that feature Rosalinas cleavage, with the design of her dress, it's an easy route to take. I really wanted to give emphasis to her butt in this one though. It helps to draw a character from all kinds of angles.
