Lovely work.

(Because you wanted a Critique)

First off, I love the composition and colors of this peice. I especially enjoy the scratchy looking brushes you used. The orange and the little white speckles add to the over all feeling of this picture. The posing is good, but I'd try to work on the girls expression a bit more. ( Basically giving her a more dynamic expression would make the picture itself more dynamic.) And the bodies seem a tad bit stiff looking.
I'm enjoying the contrast between the grays and the orange the most. The character design is also great.
Over all, it's a very good picture and keep up the great work. c:
