For Bronx native Devon Rodriguez, social media is an art form. The painter and sketch artist built a massive fan base with his hyper-realistic drawings of strangers on the New York subway. “It’s not even about the portrait, it’s about the person’s reaction,” says Rodriguez. Celebrities sit for him, too. A-list subjects have included Ben Affleck and Oprah. Brand deals include McDonald’s, Mastercard, and Verizon.
