@MadameX - yes it is hard to see from the poor quality of the photo samples. Number 4 actually has the inner corner of the lower lid appearing to end behind the inner corner of the upper lid.  That is basically the key point in any depiction of the classical epicanthic fold.

@lmckenzie - I have been looking at some of the Asian characters for Poser sold here at Renderosity, and so far, I cannot really say any particular one accurately represents the case of this topic.  I don't want to point out any specific item.

Allow me a moment to make a collage of the eyes for the out-of-the-box Asian figures made for Poser use. ie, Miki3, Miki2, Izumi of Poser 8, Satoko (by Poserism) and Tuyoko (by Have).  I included the semi-stylised Satoko and Tuyoko, because their eyes are closer to the type discussed in this topic.
