The lips are perfect, but I've never seen any image of a geisha with eye makeup like the one in Kosher's work. But realism isn't the issue. A person can be as creative as they want with their image.

There's just something off about the way the pink extends from the purple area of the makeup. Awkward I'd call it. But other than that, I can't place my finger on why the eye makeup doesn't work for me.
