The smile, I look like my mother

[ROBINDESBOIS]

Is that Ok?
Or we should say My smile is similar to my mother´s
I look like my mother as far as the smile is concerned
etc......

[chileno]

My smile is similar to my mother´s

Or "My smile looks like my mother's (smile)"

[LibraryLady]

You could say "I have my mother's smile."

[JPablo]

That sounds good to me, like in Spanish,
"Tengo la sonrisa de mi madre".
