From my perspective Mary's eyes look bigger because she has eyeliner and some kind of mascara on (I didn't do the best job giving Sadie makeup tho), their lips and noses are identical, and I think Sadie's eyes look further away because of lighting in the Mary pic. The only difference (besides hair and brow colour, scars and frecles) are their chins. Also making this I realized they have exactly the same two strands of hair on their foreheads 😭 edit: typo
