I look a lot like my Mother's Dad and while we look rather different now I look very much like my Dad did when he was my age. Same size (42 Long), same height (6'2"), same weight (185 lbs) and almost look like twins except that he had dark brown hair and brown eyes and I have reddish brown hair and gray eyes.
My brother looks most like our Mother and my sister looks most like my Dad, which is weird 'cuz she is actually rather pretty and objectively very attractive and he looks like what you would expect a football playing Army Officer to look like. She was always afraid that favoring Dad's looks she would end up looking like a russian truck driver, but it seems to have worked out well.

I look 99% like my maternal grandmother! The only difference is that she had bright blue eyes, and mine are greenish-hazel (thanks, Dad....).

She passed away before I was born, and I used to freak people out when I would say that I liked something, and it would turn out that my grandmother was the only other person who liked it!
