Yeah, but what if I want them to be bigger?

A new kid in class asked me for some advice getting proportions right in drawing portraits because he wanted to do a drawing of this girl, who apparently was "the one that got away" that he was still pining for which I thought was kind of sweet so I drew it for him to demonstrate.
Of course I also had another exchange with him where he wanted to know about getting body proportions right, and so I drew the classic Vitruvian Man example. He then asked me how it would be different if it were a woman, and so I demonstrated and basically it devolved into him wanting me to teach him how to draw boobs. So I'm not sure how sweetly romantic his final drawing wound up being.
