I guess my suggestion is, oddly enough: more colors, more rendering, more detail, more information, more contrast, more variation, more fries.
which arrives in the end at a different style, quite more difficult to animate, but that's another thing. Behind the color edits which you can take or leave, there's a lot of a)clothing ideas, about wrinkles, highlights hue variation, whatnot, and b) anatomy crits you might want to look at, mostly about curves, girly thighs and waists and other such concepts I like to think about when I am alone in the night.
