7.5 with highlights and shadows the rules of zenithal highlighting and all that jazz the highlights need to be built up to white on the paces that light hits on top and those places the sun don't shine like underbelly for example need to be glazed down to black .they both need to be exaggerated greatly! The scale we work at doesnt show shadows like full sized humans so they need to be a big contrasts by exaggerating the shades/ to yhe highlights so rule of thumb when you think your finished shade more and highlight further!
