Ancestors?

Here's a painting a talented artist made of my sister, my mom, and I, wearing our traditional Balinese costumes. No, not really! This is a painting in our hotel room and, coincidentally, they look just like us! My dad was the first one to notice. Indonesians and Filipinos really share the same blood, but what are the chances that they would look just like the three of us? I wonder if the artist used real models or painted these women from his own imagination. If they are real people, I'm pretty sure we're related!
