Is "Whom do I look like" the 'proper' way of saying "Who do I look like?" I know that second option is the most used one, but still
And you can tell that it is the right way bc if you turn the sentence around you would say, "Do I look like him?" Or "Do I look like her?" Whom stands in for Him / Her and Who stands in for He / She. I believe He / She / Who are called subject pronouns. And Him / Her / Whom are object pronouns.
