Feições translates to "features" in English, referring to the distinct parts of a face or appearance. It's a more specific and evocative word than a general term like "face."
In the song, Fernando Daniel sings, "Quando olho para ti, Vejo as minhas feições" (When I look at you, I see my features). This line beautifully conveys the deep connection and resemblance he sees in his child, highlighting the idea of shared heritage and identity.
"Prometo" is Fernando Daniel's list of promises to someone he loves deeply. He vows to hold onto every hug, to take them somewhere no one else has, and to wipe away their tears whenever they cry.
He sees his own reflection in the way this person looks at him, and even his own eyes can't fully capture what he feels for them. All he wants is for them to be happy, and wherever they go, he asks only to stay close.
The song also thanks the person's mother for bringing them into the world, calling them the greatest gift their family could ask for.
