Here's a photo of beautiful actress Lin Chi-Ling.  Her upper eyelid folds also remain visible even though they do gradually recede into the inner corner of the eye.

I'm snagging this picture.  I haven't done an Asian character since Asami for Miki 2 and that was next on my list to try.  The reference images you have here are invaluable.  When I did Kupua I used a former Miss Hawaii's features as a base to create the character because I did not want to offend anyone or create a "caricature" or stereotype.
