Sun & moon

After several drafts I finally draw this logo in Photoshop (100%). I have trouble using mouse to do this. As you can see, the line is not as smooth as I want. I've changed the sun-girl's hair a little bit, make it more curly like the sun's beam light (like in some old design). Through the girls' characteristic I tried to express:
The moon-girl: she's sleeping, calm. Also, the feeling when look at her are quiet, charmed, secret.
The sun-girl: she's awake, control, powerful also beautiful ^^.

After all, I feel it's a little like the versace's symbol or Medusa Queen.
