Their underlying cranial structure is completely different. To me, its most apparent in the lower jaw - angle of the mandible especially. The intercanthal distance is also off. Also, FLEK is more large framed, which you can even see in her cranial anatomy - she just has bigger/thicker bones. MLL looks to be very, very slight and petite. Its of my opinion that they aren't a match, but do share similar looking mouths. More photos of MLL would be helpful, but I'm fairly confident in saying these aren't a match based on that photo. Also: supraorbital ridge and orientation of the orbital socket is different. Very different. Can't change that with surgery.
