How to avoid resentment when one kid is always complimented on their looks and the other is ignored?

I have 2 amazing little boys. They are 6 and 5 and are 16 months apart.Both are gorgeous in my eyes but the oldest is the one who gets stopped when we go out. People ask if we have considered commercials or modeling. I'm not saying this to brag but these are what people say often. A few moms of girls in his first grade class or in his karate class call him their daughter's boyfriend. We thank them but don't pay much attention to it and never mention looks at home.This wouldn't be so bad if I didn't have a younger son who is noticing and asking why people don't say things about him. I don't know what to tell him. I don't want to focus to much on looks so I don't know if it's better to tell him that he's handsome too or if I should focus on other traits that make him great.I don't want him to feel like he's living in his brother's shadow. His brother is more outgoing and gets more attention in general so I worry that this will add to the problem.Please help. via /r/Parenting http://bit.ly/2EV6sVg
