How do I get this guy's attention?

He's popular, athletic, and nice. He isn't at all a jerk, but he's really quiet around people he doesn't know...like me. I've talked to him once or twice. But if I say hi to him, he'll do a head nod or something like that. Buuut, I kinda got carried away and asked what his eye color was, I looove brown eyes. That's why, hahaha. But he might think I'm weird for that. And my best friend pushed me into him today so he might think I like him... So yeah. If I talk to him, he like looks at me and stuff..? So I feel like he doesn't wanna talk to me? I don't know if that's true but yeah. He looks at me a lot. Like not A LOT but often. So yeaaah! Thanks in advance. : )
