Alia Bhatts young looks

This is not meant to bash her or anything, but do you think this puts a constraint on her. Right now she is young so she can play younger. and she targets the youth especially kids and teenagers. After watching the shaandaar trailer I feel like her acting was similar to humpty. I like her acting, but 6-7 years down the line- she won't be able to pull off such characters with such innocence I feel. What's your opinion?
