What do you think of my character's description?

He will be the love interest of my main character. His name is Gable. Please let me know what you think:

I couldn’t take my eyes off of him. He was beautiful in a way that I had never noticed in anyone else. He was tall and strong and not in that cartoonish way that most guys prefer. He was strong in mind and body, I could tell. I don’t know how I was so certain. I felt like he could do anything and do it better than anyone. He had long, light brown hair that he constantly ran his fingers through. The gesture seemed like second nature to him; a habit like biting your fingernails or twiddling your thumbs. And then there were his eyes. They were unlike any eyes I’d ever seen. They were intense and focused which made them slightly unnerving. But what really caught me was the color. It was like they didn’t know what color they wanted to be. I had a feeling I could stare at them forever and never figure out if they were grey or green. And he didn’t say much. He went about his work silently. That really didn’t bother me. At the moment, I wasn’t so great at verbal communication either. But there were a few times when I found him staring at me. Normally, when you catch someone staring at you they look away quickly, but not him. He would stare until I looked away. I wasn’t sure what to make of that and it definitely made me nervous. The problem was I couldn’t decide whether I was nervous-excited or nervous-terrified. So I did the only thing I could do. I ignored him.
