Loving you

I cleaned my drawing. I didn't like the messy background wich I'm still not sure about what to do with them and the ugly shadows from my camera. Much better!
I'm going to post this as my official work. But I'm still thinking about adding a background or not. What do you guys think? leave it or add something?
