"Your smile." Cisco said without hesitating because he'd thought about this a lot and that was what he considered it was. He never really saw Hartley smile before. Glare, frown, smirk, all that but never a real smile. When he first saw one, it melted his heart. "Then your eyes then your ass. I ranked it, I'm always right, people can fight me over this but I know what I'm talking about." With a grin, he pulled out his favourite sketch and held it out for Hartley. "I want to make something like this."
