Is there anything I can do to turn a double lid to a monolid? (Photos)

Attempting surgery to achieve this would be a mistake.  Especially to achieve Asian looking eyes, your eyes could easily be made to look more Asian with makeup.  The size and shape of your eyes and supratarsal crease (double eyelid) are not beyond the realm of what some girls achieve surgically.  

Thanks for your photos.  Your eyes are beautiful and you should leave them alone.  There are other non-surgical alternatives to achieve what your looking for. Best wishes!
